Objective:
– To show that the current is induced in a coil when magnetic lines of force cut the conductors.
Apparatus:
- Coil: 400-turns, hollow square core (Phywe)
- Coil: 1600-turns, hollow square core (Phywe)
- Galvanometer
- Bar magnet
- Short Banana leads
Method:
Terminals of the coil are connected to a galvanometer. Inserting a magnet will produce a deflection on the meter in one direction. A motionless magnet will bring the pointer to zero. Retraction of the magnet will deflect the meter pointer in the opposite direction.
