Physics Topic: Electromagnetism

1. Show an appreciation that a force might act on a current-carrying conductor placed in a magnetic field.

2. Recall and solve problems using the equation F = BIL sin(theta), with the directions as interpreted by Fleming’s left-hand rule.

3. Define magnetic flux density and the tesla.

4. Show an understanding of how the force on a current-carrying conductor can be used to measure the flux density of a magnetic field using a current balance.

5. Predict the direction of the force on a charge moving in a magnetic field.

6. *Recall and solve problems using F = BQv sin(theta).

7. *Describe and analyse deflections of beams of charged particles by uniform electric and uniform magnetic fields.

8. *Explain how electric and magnetic fields can be used in velocity selection for charged particles.

9. Sketch flux patterns due to a long straight wire, a flat circular coil and a long solenoid.

10. Show an understanding that the field due to a solenoid may be influenced by the presence of ferrous core.

11. Explain the forces between current-carrying conductors and predict the direction of the forces.
