To demonstrate the conversion of mechanical into electrical energy.
- A.C. generator
- Demonstration galvanometer
- Half Rola Permanent magnet
The apparatus consists of a coil of wire free to rotate about a horizontal axis. The ends of the coil are connected to slip rings. Rotating the coil in the earths magnetic field produces an alternating EMF that is displayed by the galvanometer deflections
The deflection magnitude may be increased by the addition of a Half Rola permanent magnet beside the coil whereupon the relationship between the field direction and induced EMF becomes more obvious.
