1. I don't know hardly any phy5 experiments, my teacher hasn't taught me any. I've just realised that i don't know hardly any.

Can someone tell me how to do this:

2. A current-carrying conductor is situated in a magnetic field. Describe how you could demonstrate that the magnitude of the force on the conductor is directly proportional to the magnitude of the current in it. You may wish to include a diagram in your answer. You may be awarded a mark for the clarity of your answer. (4)
2. put the conductor on a pan balance, vary the current and measure the change in force on the balance. plot the change in force against the current, check that the line of best fit is straight through the origin.
3. how can you vary the current? Variable resistor?
4. Also, which other phy5 experiments are there for me to revise?
5. (Original post by nas7232)

Yep
6. Hall probe, Capacitor discharge, Magnetic effect of a steady current near straight wire,
Electromagnetic induction, solenoid and bar magnet, magnetic flux density,
