Which statement is INCORRECT for mutual inductance?
1
The change in the strength of the current in the coil is opposed by the coil itself by inducing an EMF.
2
The induced current developed in the neighbouring coil opposes the decay of the current in the coil when the main current in the coil decreases.
3
In mutual inductance, out of the two coils, one coil opposes the change in the strength of the current flowing in the other coil.
4
The induced current developed in the neighbouring coil opposes the growth of current in the coil when the main current in the coil increases.
