Magnetic moment. Answer: A. Self-inductance is that phenomenon in which charge in electric current in a coil produces an induced emf in the coil itself. Q2. Two coils A and B have L= 2×10 -2 Henry. If the current in the primary is i = 5 sin 10πθ then maximum value of emf induced in coil B is: Π volt.
We have the formula for inductance as, L = V d I d t. Hence, dimensional formula for inductance is [L] = [M L 2 T − 3 A − 1 A T − 1] = [M L 2 T − 2 A − 2]
(i) Mutual inductance of two coils is equal to the e. m. f induced in one coil when when rate of changes of current through the other coil is unity. ( i i ) Mutual inductance of two coils is defined as the magnetic flux linked with the secondary coil when the current in primary coil is 1 ampere .

Thus the coefficient of mutual inductance is equal to the magnetic flux linked with secondary coil when the current flow in a primary coil is unity, from equation(2), $$ \varepsilon _2= M\dfrac{dI_1}{dt } $$
A circuit contains two inductors of self-inductance L1 and L2 in series (see figure). If M is the mutual inductance, then the effective inductance of the circuit shown will be. Find the mutual inductance of the two c0-planar sqare coils as shown in figure (b<<l) Diagram. Two circular coil can be arranged in any of the three situations shown in ...
The self inductance of two coils P and S are L 1 and L 2. The coupling between them is ideal. The coupling between them is ideal. Show that the mutual inductance between these coils is M = √ L 1 L 2 .
The bridge method commonly used for finding mutual inductance is. The mutual inductance between two coupled coils is 25mH. If the turn in one coil is doubled and that in the other is halved, then the mutual inductance will become.
If R 1 ≫ R 2, the mutual inductance M between them will be directly proportional to. View Solution. Q4.
Mutual inductance of two coils can be increased by . decreasing the number of turns in the coils; ...
