This module presents the discovery of magnetism and some of the fundamental experiments and laws showing the relationship between electricity and magnetism.
Objective
1. discuss the history of magnetism.
2. describe the different kinds of magnets and their properties.
3. list some uses of permanent magnets.
4. explain what is meant by magnetic field and how it is detected.
5. describe magnetic field.
6. show how magnetic fields and electric currents are related.
7. describe the way an electromagnet is made and the kind of magnetic field it
produces.
8. state the effect that a magnetic field has on electric current.
9. recognize the conditions under which a magnetic field can be used to produce
electric current.
10. explain how the interaction of magnetic fields produces movement in a motor.
11. illustrate the components of a typical household electrical circuit.
12. describe the functions of fuses and circuit breakers and tell how they work.
13. describe a generator and the way it produces electric energy.
14. describe a transformer and explain how it works.
