Question
PC 1. The figure shows a ring of copper with its plane perpendicular to the axis of the nearby rod-shaped magnet. it For each of the situations described below, indicate whether there will or will not be a current induced in the ring and justify your reasoning, drawing pictures if necessary. The magnet is moved horizontally toward the left. The ring is moved away from the magnet. The ring is rotated around any of its diameters. The magnet is moved up or down. The ring is rotated around its center in the plane in which it lies.Explanation / Answer
a)
here if the magnet is moving horizontally towards the left:
magnetic flux through ring changes with respect time
hence curent induces
b)
if the ring is moved away from the magnet again
magnetic flux through ring changes with respect time
hence curent induces
c)
curent induces because number of fild lines crossing the area of ring changes if you rotate the ring around any of its diametrs hence rate of flux chenges
d)
again curent induces because number of fild lines crossing the area of ring changes hence
hence rate of flux chenges
e)
here current will not be induces because flux through area of the ring not changing
