Making Electricity Using Magnets

Here is the solenoid (coil of wire)

Here is a picture of electromagnetic induction in action

This process is called electromagnetic induction

Note: another name for a coil of wire is a solenoidNote: Electromagnetic induction is how most electricity is generated

Magnets and a coil of wire can create electrical current

The magnet has to move through (or around) the coil

The coil has to move through (or around) the magnetor

See the diagram below Notice that the bar magnet is moving through the coil of wire

Quick Review

SPI 0807:12.1 Electromagnetic Induction

1) The two pictures below both show electromagnet induction.

How would you increase the electrical current? (p439: Fig 2, Letter B)

Picture 01 Picture 02

3) Picture 02 shows an electrical generator.

Page 439 describes this process in two parts. What are they?

2) Picture 01 shows a bar magnet being pushed through a solenoid.

What are the 5 key components of a generator ? (p440: Fig 4)

Picture 01 Picture 02

Part 1: You must have a magnet and coil of wirePart 2: You must move the magnet through or around the coil…

OR…move the coil over or around the magnet
