How does electricity create magnetic power?

Answer 1

Electricity and magnetism are the two facets of the electromagnetism force.

It means that where ever there is electricity flowing in a conductor there is

also a magnetic field produced. The intensity of the electric current flowing in

a wire determine the intensity of the magnetic field that arise near the wire.

So here's one easy way to make an electromagnet. You take a big iron nail

(the iron here act like a concentrator of the magnetic field). Then you make

as many turn you can with some insulated copper wire around the nail (you

can find very nice wire in the windings of an old transformer). You plug both

ends of the wire to a D size battery after removing the insulation at the ends

of the wire. When connected, try your new electromagnet on small iron nails.

Answer 2

An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current is turned off. Electromagnets are widely used as components of other electrical devices, such as motors, generators, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment, as well as being employed as industrial lifting electromagnets for picking up and moving heavy iron objects like scrap iron.

Answer 3

A coil of wire wound around a soft iron core, and supplied with an electric current, will produce an electromagnet

Answer 4

you just create it
