Lesson Plan: Magnetism and Electricity: Electromagnets
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe how electromagnets are made and used.
Objectives
Students will be able to
- explain that when an electric current flows through a wire, a magnetic field is produced,
- define an electromagnet,
- describe how to build a simple electromagnet,
- describe how electromagnets can be made stronger,
- compare an electromagnet to a permanent magnet,
- identify uses of electromagnets.
Prerequisites
Students should already be familiar with
- what a magnet is,
- what a compass is,
- the names of common magnetic and nonmagnetic materials,
- electric circuits.
Exclusions
Students will not cover
- electromagnetic induction.
