A device that produces a magnetic field by wrapping wire into a coil is a?
an electromagnet
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 device use magnet and electricity?

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.
Is an electromagnet likely to be attracted to a magnet?
An electromagnet is simply a device that will create a magnetic field when electricity is run through it (basically a normal magnet, but you need to plug it in). Depending on the magnetic charges of the electromagnet and the regular magnet, it should either attract or repulse like magnets normally do to one another.

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.
What is a device that has an iron center wrapped in coil of wires?
This is a basic description of an electromagnet. Apply a voltage (direct current) to the coil, and a magnetic field will develop around the coil and be "conducted" through the iron core to create that electromagnet.
What happen to a electromagnet if you switch the current off?
When we turn of the current in an electromagnet then electromagnet looses its magnetic property,provided the material used inside the current carrying solenoid is soft iron core. If, the material is steel then after the current is turned the magnetism propety still prevails and hence steel becomes a permanent magnet.

Electromagnet
A safety device that uses an electromagnet to shut off the circuit is called a?
A safety device that uses an electromagnet to shut off the circuit is called a contactor.
What is a compass and what does it do?
1. A device using a magnetized needle to point to the direction of magnetic north (which is actually a south pole, but that's another story). 2. A device for drawing circles.
