Question

The direction of force on a current carrying conductor placed in a magnetic field can be reversed by reversing the direction of current flowing in the conductor. True/False?

Answer 1

The force experience by a current carrying conductor placed in a magnetic field is :
$\overrightarrow{F}=I(\overrightarrow{l}\times \overrightarrow{B})=IlB\sin \theta$
If the direction of current flow is reversed then the $\overrightarrow{v}$ will also change its direction and eventually the direction of force will also be reversed.

Hence True.
