Question

in an electromagnet, the wire to make the coil should be insulated ( state whether true or false)​

Answer 1

Explanation:

true .... it's is true ...

Answer 2

Answer:

it is true

An Electromagnet is called as a temporary magnet, because electromagnet is made up of insulated copper wire wrapped around soft iron, which allows current to flow in it and at that moment iron gains it magnetic properties and when the current is switched off, then there will be no flow of current and hence iron loses its magnetic properties.  

Hence it works temporarily as long as electric current flows in a conductor and hence known as temporary magnet. .
