Induction hobs are a type of stovetop that uses electricity to heat the base of a pan directly through a magnetic circuit. This means that only certain types of pans work on an induction hob. Halogen hobs, on the other hand, are a type of electric ceramic hob that uses a powerful bulb filled with halogen gas to create infrared radiation and heat saucepans. Unlike induction hobs, halogen hobs do not require special pans and can work with any type of cookware made of conductive materials. This article will explore the key differences between halogen and induction hobs, and whether halogen pans can be used on induction hobs.

- Induction cooking is more energy-efficient than gas or electric hobs
Induction hobs heat the pan, not the stove
Induction hobs use electricity to heat the base of the pan directly through a magnetic circuit, rather than heating the hob surface. This means that only the pan gets hot, and not the stove itself. This makes induction hobs safer than traditional gas and electric hobs, as there is no open flame and the surrounding area remains cool to the touch.
Induction hobs are also more energy-efficient than other types of hobs, as they only heat the cookware, reducing energy usage. This also means that food heats up more quickly, and the hob is more responsive to changes in temperature control. The speed and precision of induction hobs mean you can often use a lower heat setting than you would with other hobs.
To use an induction hob, you need to have a pan made of a magnetic material, such as cast iron, stainless steel, or nickel. You can test if a pan is compatible with an induction hob by placing a magnet on its base; if the magnet sticks, the pan will work on an induction hob. Some non-magnetic pans can be used with a heat diffuser, which is placed under the pan on the hob.
Halogen hobs, unlike induction hobs, use a powerful bulb filled with halogen gas to create radiant heat. This heats the saucepan directly but also heats the surface of the hob, which further heats the cookware through conduction. Halogen hobs are faster and more efficient than traditional electric hobs, but induction hobs are even faster and more efficient, as they transfer more heat to the cookware.

Pans with magnetic properties are required for induction hobs
Induction hobs create a magnetic field between the hob and the pan, which directly heats the pan rather than the hob surface. This makes induction hobs more energy-efficient than gas or electric hobs, as well as safer, as there is no open flame and the surrounding area remains cool to the touch.
However, this also means that only pans with magnetic properties will work on an induction hob. Pans made from cast iron, stainless steel, or enamel-coated cookware with a magnetic base are all induction-compatible. If you're unsure whether your pan is made from a magnetic metal, you can test it by placing a magnet on its base. If the magnet sticks, the pan will work on an induction hob.
Some non-magnetic pans, such as those made from aluminium, copper, or glass, may still be compatible if they have a magnetic layer added to the base. Manufacturers often indicate compatibility with induction hobs by including a symbol on the bottom of the pan or noting it on the packaging. This symbol often looks like a horizontal zig-zag or a coil.
It is important to note that the bottom of the pan must make full contact with the induction hob's surface for efficient heating. Pans with warped or uneven bottoms may not work effectively.

Pans made of aluminium, brass and copper won't work unless they have ferrous bases
Induction hobs are a type of stovetop that uses electricity to heat the base of the pan directly through a magnetic circuit. Pans made of aluminium, brass, and copper will not work on an induction hob unless they have ferrous bases. This is because induction cooking requires pans to be made of a magnetic material, such as iron or iron-based steel.
Ferrous means an alloy that contains iron in reasonable amounts. Pans made of aluminium, brass, and copper typically do not contain iron and are therefore not compatible with induction hobs. However, some manufacturers offer aluminium, brass, and copper pans with a magnetized base specifically designed for induction hobs. These pans have a layer on the bottom with magnetic properties, allowing them to work on induction cooktops.
To determine if a pan is compatible with an induction hob, you can perform a simple test by holding a magnet to the bottom of the pan. If the magnet sticks, the pan contains magnetic material and will work on an induction hob. If there is no attraction between the magnet and the pan, the pan does not contain the right metals and will not generate heat on an induction cooktop.
It is important to note that not all stainless steel pans are compatible with induction hobs. Stainless steel with a high nickel content or in an annealed state will not work as it blocks or reduces the magnetic field. Therefore, when purchasing stainless steel pans for induction hobs, ensure they are specifically designed for induction cooking.

Cast iron, enamelled cast iron and some stainless steel pans are induction-compatible
Induction hobs use electromagnetic fields to generate heat directly to the bottom of the cookware, rather than heating the hob surface. This means that only certain materials will work on an induction hob. The key is magnetism; induction hobs will only work with cookware made of ferromagnetic metal. Cast iron, enamelled cast iron, and some stainless steel pans are induction-compatible.
Cast iron is a ferromagnetic metal, so cast iron pans will work on an induction hob. Pans made from enamelled cast iron will also work on an induction hob. Enamel is a type of glass that has been fused with other materials, often cast iron, to make it stronger and more durable. Enamelled cast iron pans combine the benefits of cast iron with the non-stick and easy-to-clean surface of enamel.
Some stainless steel pans are also induction-compatible. However, stainless steel can be made with a variety of metals, and a high nickel content will block the magnetic field. Therefore, it is important to check that the stainless steel pan has magnetic properties before using it on an induction hob. One way to do this is to hold a magnet to the bottom of the pan; if the magnet sticks, the pan will work on an induction hob.
It is worth noting that while induction hobs offer many benefits, such as improved energy efficiency, safety, and temperature control, they do require specific cookware. This may increase the costs of switching to an induction hob if you do not already have compatible cookware.

Induction cooking is more energy-efficient than gas or electric hobs
Induction hobs are more energy-efficient than gas or electric hobs. Induction hobs use electricity to power a magnetic circuit that directly heats the base of the pan. This means that only the cookware is heated, not the hob surface, reducing energy usage. The surface of a gas or electric hob, on the other hand, must be heated first, and then the heat is transferred to the pan, resulting in energy loss.
In one experiment, an induction hob took 5.8 seconds to boil water, while a gas stove took 8.3 seconds. This demonstrates that induction cooking is faster and more efficient, with less energy wasted. Induction hobs are also safer as the surface remains cool to the touch, reducing the risk of burns.
The energy efficiency of induction hobs is further enhanced by their precise temperature control. Unlike gas hobs, induction hobs offer more precise temperature settings, reducing the risk of overcooking. This means you can cook at lower temperatures, saving energy. Induction hobs are also more responsive to temperature changes, allowing for better control and precision in cooking.
The environmental benefits of induction cooking are significant. Induction hobs are more environmentally friendly than gas or electric hobs, producing lower carbon emissions. Gas hobs use natural gas, a fossil fuel that contributes to global warming, whereas induction hobs can be powered by renewable energy sources. The government is committed to reducing emissions by phasing out gas cookers and hobs in new build homes by 2025.
While induction hobs offer energy efficiency and environmental benefits, there are some considerations. Switching to induction can be expensive, and you may need to purchase compatible cookware. Induction hobs require magnetic cookware, so pans made from copper, stainless steel, aluminium, or glass may not be suitable without an induction plate. However, manufacturers have begun adding magnetic layers to pans, and induction cookware has become widely available.

Frequently asked questions
An induction hob is a type of stove-top that is powered by electricity. It uses magnetic conduction to directly heat the base of the pan, rather than the hob surface, making it more energy-efficient than traditional gas or electric hobs.
Pans with magnetic properties are required for induction hobs as they need to be able to conduct electricity. Cast iron, enameled cast iron, and many types of stainless steel cookware are compatible. Pans with flat bases are also important so they can properly receive the magnetic charge.
A simple way to check if your pan is compatible is to place a magnet on its base. If the magnet sticks, the pan will work on an induction hob. Some manufacturers also include an "induction compatible" symbol on the bottom of their cookware or on the packaging.
Yes, there are products like a stainless steel induction hob heat diffuser that can be placed on the cooktop under the pan. However, it is recommended to use compatible pans for the best results.
