The functions provided by cooktops can vary however as they are electrical they can provide a number of automatic functions that are not possible with other heating technology.
Induction cooktops allow much better control over heating and can even allow the user to set a temperature for the cookware base making heat control much more precise. The cooktop will also detect when the pot has been removed and turn off the induction and give a warning.
Cooktops will also detect when the pot gets too hot and turn off which saves damaging the cookware.
Induction Cooktops have ceramic glass tops which makes them very easy to clean.
The glass top is just a spacer to support the cookware over the electric coils so it does not heat up the same way other cooking surfaces do. they do get hot but that is only because they are in contact with the hot cookware.
The method of energy transfer is way more efficient with methods such as gas losing a significant portion of energy as heat and light into the environment around the cookware. induction cooktops only heat the base of the cookware directly so there is very little loss in the transfer.
