A current flows in a wire running between the S and N poles of a magnet lying horizontally shown in the figure below:The force on the wire due to the magnet is directed: a) from N to S b) from S to N c) vertically downwards d) vertically upwards
A current flows in a wire running between the S and N poles of a magnet lying horizontally shown in the figure below:The force on the wire due to the magnet is directed: a) from N to S b) from S to N c) vertically downwards d) vertically upwards

Answer:

The correct option is c) vertically downwards

Explanation:

Using Fleming’s left-hand rule, the force on the wire should be vertical.
The index finger indicates the direction of the magnetic field, the middle finger represents the direction of the current, and the thumb represents the direction of the force received by the wire.
