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.
