Solution

The correct option is C anticlockwise direction
The direction of magnetic field in the conductor can be found out by Right hand thumb rule. As the direction of the current is in upward and if we keep our thumb along the direction of the current then the curl fingers will give the direction of the magnetic field which is anticlockwise direction.

Q. If in a straight conductor, the current flows from north pole to south pole. What will be the direction of magnetic lines of force?

Q. A straight current-carrying conductor is placed in such a way that the current in the conductor flows in the direction out of the plane of the paper. The conductor is placed between two poles of two magnets, as shown. The conductor will experience a force in the direction towards.

The black conductor is carrying a current in vertically upward direction and a magnet is placed next to it as shown. Now it is known that the magnet experiences force. What should be the direction of current in another wire (shown in green) in order to keep the magnet in place? (Consider the force only on the north pole)
