Question
The loops in the figure move into or out of the field which is along the inward normal to the plane of the paper. Indicate the direction of currents in loops 1, 2, 3,4.
Solution
The magnetic flux through the loop in fig. 1 decreases, due to the outward motion of the loop from the magnetic field because, of which the induced current must be clockwise so as to increase the flux. Due to the same reason induced currents in figure 3 and 4 are clockwise.
In figure 2 current must be anticlockwise as flux is increasing because as seen motion of the loop is into the region of the magnetic field.
