Question

how does electricity produce magnetism

Answer 1

An electron, with its negative charge, is surrounded by an electromagnetic field. Normally, in most materials, this field is canceled out by the random positioning of all of the other electrons in the material.

If these electrons are aligned, the material will become a magnet with the magnetic fields aligned toward one end of the material.

If the electrons are traveling through the material (current or electrical flow) the magnetic field will be moving with the electrons and will surround the wire (refer to "right hand rule")
If the wire is coiled around a piece of iron, for instance, this magnetic field will become very strong and align the electrons in the iron - thus magnetizing the iron.

Answer 2

The problem is electricity and magnetism are mysteriously two effects of the same thing, hence the field of study is called electromagnetism. A current travelling in a horizontal loop or spiral will produce a magnetic field spewing veritcally from the center of the loop. However, a simple wire carrying an electrical current will produce a circular magnetic field surrounding the wire. Or a magnet passing through a coil will produce a current, etc. The equations that govern the relationship are Maxwell's equations, but you need calculus to understand them. There are simpler versions, like Ampere's Law, the Biot-Savart Law, Faraday's, etc. Unfortunately it's heavy on the math except the simplest cases.

Answer 3

I think you mean "how does electricity induce magnetism?"
When electricity travels in a circular motion it creates a magnetic field. Also, if you think about it backwards, when magnets move circularly around metal they produce electric current like how an alternator in a car produces electricity.
