Why nichrome wire is used as heating element?

Nichrome wire is used as a heating element because it is very stable, even at high temperatures. Unlike other metals, it will not melt even when generating large amounts of heat. Ironically, nichrome actually has low electrical resistance, the property that causes the wire to heat.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
