Questions
Q1
- a)[7]
Derive an expression for Energy stored per unit volume in the magnetic field.
- b)[8]
Two coils having turns 1000 and 1500 are placed on common magnetic circuit. A current of 5A in coil-1 produces a flux of 0.2 mWb and 80% of this flux links to coil-2 . Find i) Self Inductance of coil-1 ii) Mutual Inductance between them iii) If this current in first coil is interrupted in 0.01 sec find emf induced in coil-1 and coil-2
