Question

The force experienced by a current-carrying conductor placed in a magnetic is the largest when the angle between the conductor and the magnetic field is:

(a) ${45}^o$ (b) ${60}^o$ (c) ${90}^o$ (d) ${180}^o$

Answer 1

The force experienced by a current-carrying conductor placed in a magnetic is the largest when the angle between the conductor and the magnetic field is ${90}^o$. So, the correct choice is (c).
