EM6.7 Magnetic Forces
This is a general magnetic interaction. A magnet is hanging in the air. See how the magnet responds when another magnet and a piece of iron are brought nearby . Place a solenoid below the magnet and attach it to a power supply. See how the magnet reacts when the power supply is turned on. See how the magnet reacts when the power supply is turned on. The same could be done with a suspended solenoid connected to a big galvanometer. See how the current changes when a magnet is brought nearby and inserted, when another solenoid is turned on below it, and how the iron's presence affects it.
