# Making an Electromagnet?

An electromagnet is a magnet that operates on electricity. Unlike the permanent magnets, electromagnets' strength can easily be transformed by changing the amount of electric current that passes through it. The poles of electromagnets can as well be overturned by reversing the flow of electricity.

An electromagnet is a type of material with a magnetic field that is produced by the flow of electric current that disappears when the field disappears. It is widely used as a component of other electrical devices, as well as being employed as in industrial lifting equipments for picking up and moving heavy iron objects.
An electromagnet is a magnet that can be switched on and off with electricity. Electromagnets show that electricity can make magnetism, which is therefore caused when the current flows.
An electromagnet is a kind of magnet who has it's magnetic field produced only when there is an electric current flowing at that moment. Once the electric current stops flowing, the electromagnet's field stops. You can find more information here: http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/elemag.html
