1. What is a permanent magnet?
Give 3 examples of permanent magnets.
2. What the poles of a magnet? How many
3. Like poles _________ but unlike poles __________
Go over drill
Homework due on Friday
Read out objective
Students will be able to conduct an experiment to study
a. the effect of electromagnet on a permanent magnet and also
b. to compare the electromagnet to a permanent magnet,
in order to understand the role of magnets in every electrical devices that creates motion.
Students will watch a video/ demo software to view the effect of permanent/ electromagnet on a closed coil.
Students will carry out experiments ( 15.2 Electromagnets, page 117-118 of Investigation physics) to study
Section 15.1 Reviewing Concepts
1. The north pole of a permanent magnet ________ south pole of another magnet (attracts/repels). 2. The south pole of a permanent magnet ________ north pole of another magnet (attracts/repels). 3. What is an electromagnet?
