Self-Induction Self-induction is the property of a coil by virtue of which the coil opposes any change in the strength of current flowing through it by inducing an emf in itself. This induced emf is also called back emf. When the current in a coil is switched ON, then the self induction opposes the growth of the current and when it is switch OFF, then the self-induction opposes the decay of the current.Calculate the inductance of an air core solenoid containing 300 turns, if length of solenoid is `12pi cm` and its cross-sectional area is `4
A long solenoid has 1000 turns. When a current of `4 A` flows through it, the magnetic flux linked with each turn of the solenoid is `4 xx 10^(-3)Wb`. The self-inductance of the solenoid

Moving Coil GalvanometerMoving coil galvanometer operates on Permanent Magnet Moving Coil (PMMC) mechanism and was designed by the scientist D’arsonval.Moving coil galvanometers are of two types (i) Suspended coil (ii) Pivoted coil type or tangent galvanometer.Its working is based on the fact that when a current carrying coil is placed in a magnetic field, it experiences a torque. This torque tends to rotate the coil about its axis of suspension in such a way that the m agnetic flux passing through the coil is maximum .In a moving coil galvanometer, having a coil of A-turns of area A and carrying
