Q.

A rectangular conducting loop of length 4cm and width 2cm is in the xy -plane, as shown in the figure. It is being moved away from a thin and long conducting wire along the direction  32x^+12y^ with a constant speed v. The wire is carrying a steady current I=10 A in the positive x-direction. A current of 10 μA flows through the loop when it is at a distance d=4 cm from the wire. If the resistance of the loop is 0.1Ω, then the value of v is _______ ms−1.
[Given: The permeability of free space  μ0=4π×107NA2

Detailed Solution

Induced emf depends on velocity along y axis
Total induced emf is  VyB1lVyB2l=ε
VylB1B2=εVsinθB1B2l=ε
v2B1B2l=εv2μ0i2πd1μ0i2πd2l=ε oil4π1d11d2=ε
Now i , Putting thevalues we get v=4
