प्रश्न

A current flows in a wire running between the S and N poles of a magnet lying horizontally as shown in Figure below: 

The force on the wire due to the magnet is directed: 

fron N to S
 from S to N
 vertically downwards
 vertically upwards

उत्तर

 vertically downwards
Using Fleming's left-hand rule, we find that the force on wire should act vertically downwards.
