Practise deciding how speed, field strength, coil turns and motion affect the size of an induced e.m.f. or galvanometer deflection.
How this is tested
- predict a larger deflection when the magnet or wire moves faster
- compare induced e.m.f. for stronger magnets, more coil turns or weaker fields
- state that a stationary magnet in a coil gives no induced voltage
