A current carrying conductor is placed in a magnetic field perpendicular to the direction of field. Is there any force acting on the conductor? Explain.

In the given figure what is the direction of the force on the current-carrying conductor?

The figure shows a horse-shoe magnet placed along geographics west-east and a horizontal conductor carrying current along geographic south-north. Find the direction of magnetic force on the conductor.

The figure shows a rectangular current-carrying coil $PQRS$ placed between the poles of a horse-shoe magnet producing field $B$. Write magnitude and direction of the force on each of the parts$PR$,$RS$, $SQ$ and  $QP$ of the coil.
