Warming Up a Hair Dryer
Most hair dryers use bare, coiled nichrome wire wound around mica boards for insulation as their heating element.
Nickel and chromium are the two metals that make up nichrome wire. This alloy is found in the heating components of many domestic appliances, such as toasters and curling irons. Nichrome wire generates heat well due to two characteristics:
When it comes to conducting electricity, it's not as good as copper wire. Because of this, the alloy has sufficient resistance to heat up from all of the current passing through it.

Heat does not cause it to oxidize. At the temperatures seen in hair dryers and toasters, other metals, such as iron, rust very rapidly.
The design of the hair dryer shell forces the airflow produced by the fan through the ...
