MODULE 1: ELECTRICITY AND MAGNETISM (cont’d)

SPECIFIC OBJECTIVES EXPLANATORY NOTES SUGGESTED PRACTICAL
ACTIVITIES

Magnetic Forces (cont’d)

Students should be able to:

6.4. predict the direction of the Use Fleming’s Left-Hand
force on a charge moving in Rule and treat the moving
a magnetic field; charge as an electric
current.

Qualitative discussion of
the trapping of charged
particles by magnetic fields
with specific mention of
earth’s magnetic field and
the Van Allen radiation belt.

6.5. use the expression
F = BQvsinθ to solve
problems;

6.6. solve problems involving
charged particles moving in
mutually perpendicular
electric and magnetic fields;

6.7. describe the effect of a soft Compare this effect with Make a small electro
iron core on the magnetic that of the dielectric in a magnet with varying cores
field due to a solenoid; capacitor. and see how many paper
clips can be picked up.

See Appendix II for
suggested practical activity.

6.8. explain the principle of the Uses in door locks, switches
electromagnet; and other applications.

6.9. explain the origin of the
forces between current-
carrying conductors;

6.10. predict the direction of the
forces;
