Two circular loops `P` and `Q` are placed with their planes paraller to each other. A current is flowing through `P` . If this current is increasesed, then

Two similar circular loops of radius R are lying concentrically with their planes at right angles to each other. The currents flowing in them are I and Isqrt(3) respectively. The magnetic field at the centre of the coil is

Two coils P and Q are kept near each other. When no current flows through coil P and current increases in coil Q at the rate 10 A//s , the emf in coil P is 15 mV. When coil Q carries no current and current of 1.8 A flows through coil P, the magnetic flux linked with the coil Q is

Two loops carrying current in opposite sence placed paralled to each other are moved closer to each other. Then the current

Two circular loops P and Q are concentric and coplanar as shown in figure. The loop Q is smaller than. P . If the current I_1 flowing i loop P is decreasing with time, then the curren I_2 in the loop Q
