- #2-aA wire of irregular shape turning into a circular shape;
(b) A circular loop being deformed into a narrow straight wire.
(b) A circular loop being deformed into a narrow straight wire.
Ans : When the shape of the wire changes, the flux piercing through the unit surface area increases. As a result, the induced current produces an opposing flux. Hence, the induced current flows along adcb.
(b) When the shape of a circular loop is deformed into a narrow straight wire, the flux piercing the surface decreases. Hence, the induced current flows along
(b) When the shape of a circular loop is deformed into a narrow straight wire, the flux piercing the surface decreases. Hence, the induced current flows along
