Why is an electromagnet considered to be a temporary magnet?
An electromagnet acts as a magnet only while electricity is passing through the coil. Once the electricity is turned off, the electromagnet ceases being a magnet. Electromagnets are much used in scrapyards. Attached to a crane, metal is picked up and deposited into railway wagons, or road haulage vehicles, to be sent for recycling.

What is elelctromagnets?
Electromagnet is a device consisting of a core of magnetic material such as iron, surrounded by a coil through which an electric current is passed to magnetize the core.
Give an example of an electromagnet?
An example of an electromagnet can be a car, generator, and the "yoke" of a tv has 2 electromagnets. Any device that is made to be magnetic by passing an electric current though the device.
What is the Simplest protective device for an electric current?
A fuse is the simplest protective device for over current in an electric circuit.
A device formed from an iron core wrapped in current-carrying wire is?
That can be a 'solenoid' or an 'electromagnet'.
