Predict the direction of induced current in the situations described by the following figures (a) to (f). |
|
Answer» Solution :a. By Lenz.s LAW, the FACE of the oil towards the south pole of the magnet opposes the south pole. So this face should behave as south pole. Hence the current flows along qrpq. b. SIMILAR to the above reason the current flows along yzxy and along prqp. c. When the coil is energised. with a cell the incresaing current produces an INVERSE current in the nearby coil along yzxy. d. Similar to the above reason the current flows along zyxz. e. By Lenz.s law current is along xryx. F. Field lines being along the plane of the loop, there is no induced current. |
