Magnetic Field of a Coil of Wire

Moving charges (i.e. electrical current) create magnetic fields. This video demonstrates this using a battery, a coil of wire, and a compass.

No, feeding it direct current (DC) from the battery will only produce a stationary magnetic field. Alternating current (AC) would create EM waves, as the coil acts as an antenna.

[JeffRegester]

Probably not. This magnetic field isn't very strong, and anyway a calculator doesn't have magnetically-operated parts like a disk drive that are susceptible to magnetic fields.

And why are you needing protection from plasma?

[derre98]

Are you sure your coil has thick enough wire?-)

[iampaco]

i think he wants to protect himself from an alien attack...now I'm curious as well

[abpccpba]

A single wire will demonstrate the same thing.

Interesting....

[Begbucks]

Thanks!

LOL. This responds to compass - on the earth's magnetic field - on to magnetic field of a coil!

I Really Like The Video From Your Magnetic Field of a Coil of Wire

[cenedywong]

Your Video Is Very Useful Sharing This video demonstrates this using a battery, a coil of wire, and a compass.

Everyone is saying things i dont even understand! Can you it in simple and uunderstandable words plsss wahahha XD
