UNIT 2
MODULE 1: ELECTRICITY AND MAGNETISM (cont’d)

SPECIFIC OBJECTIVES EXPLANATORY NOTES SUGGESTED PRACTICAL
ACTIVITIES

Magnetic Forces (cont’d)

Students should be able to:

6.11. explain the Hall effect; and, In developing the
explanation, refer to
Specific Objective 6.5.

6.12. use the Hall probe to show
variations of flux density.

7. Electromagnetic Induction

Students should be able to:

7.1. explain magnetic flux;

7.2. use the equation
Φ = BA to solve problems;

7.3. interpret experiments which Conduct investigations on
demonstrate the relationship effects obtained when:
between the magnitude and
direction of an induced e.m.f. (a) bar magnet moves
and the change of flux linkage inside a solenoid;
producing the e.m.f.;
(b) two flat coils move
with respect to
each other;

(c) bar magnet moves
with respect to flat
coil;

(d) one solenoid moves
inside another; and,

(e) solenoid moves
inside a flat coil.

In your explanation, refer to
Specific Objective 7.5.
