प्रश्न

A horizontal wire carries a current as shown in Figure below between magnetic poles N and S: 

  

Is the direction of the force on the wire due to the magnet:

(a) in the direction the current
(b) vertically downwards
(c) opposite to the current direction
(d) vertically upwards

उत्तर

vertically upwards
Applying Fleming's left-hand rule, we find that the force on the wire will act vertically upward.
