5K10.20 COIL MAGNET AND GALVANOMETER
A magnet moving through a coil causes a deflection in a galvanometer.
Keep magnet away from other magnets.
The meter movement can be damaged by moving the magnet too quickly.
Rotating a coil of wire between the poles of a magnet causes a deflection in a galvanometer.
Increasing or decreasing the size of the coil also causes a deflection.
Keep magnet at least 1/2 m away from all other ferromagnetic materials.
