Electricity and Magnetism

What is closely linked?

Magnetism and Electricity

What do moving charges produce?

Magnetic Fields

From circuit breakers to transformers, from motors to generators, from microphones to door bells:

The interplay between electricity and magnetism has proven useful in a range of applications

A current carrying wire generates:

It’s own magnetic field

The strength of the field depends on:

The amount of current flowing in the wires

When the wires are wrapped around a ferrous material and a current is passed through the wires:

The resulting magnetic field magnetizes the iron core, producing an electromagnet

This included magnetism is the:

Basic principle behind many of the aforementioned electrical devices
