Question

A current-carrying conductor when placed in a magnetic field always experiences a force. Is the given statement true or false?

Answer 1

The force experience by a current carrying conductor placed in a magnetic field is :
$\overrightarrow{F}=q(\overrightarrow{v}\times \overrightarrow{B})=qvBsin\theta$
If the direction of current flow and the direction of magnetic field become same($\theta =0^{\circ }$) or exactly opposite ($\theta ={180}^{\circ }$) then the force experienced by it will be zero.
So the given statement is false.
