Currents and magnetic fields

Moving charged particles produce magnetic fields .

A current in a wire produces a magnetic field around the wire.

A moving electron also produces a magnetic field.

Similarly, magnetic fields interact with charged particles . A charged particle that moves through a magnetic field will experience a force.

An electron in a magnetic field will follow a curved path!

Electricity and magnetism are fundamentally connected to each other. The relationship between electricity and magnetism is called electromagnetism.

This is a Tesla coil. It uses alternating currents and magnetic fields to produce impressive lightning-like effects.
