Magnetic Force on Current-Carrying Wire Video Lessons

Concept

# Problem: A current carrying wire is in a uniform magnetic field B. Under which circumstances does the force generated by the field on the current carrying wire become zero?

###### FREE Expert Solution

Magnetic force on a current-carrying conductor:

$\overline{){{\mathbf{F}}}_{{\mathbf{B}}}{\mathbf{=}}{\mathbf{B}}{\mathbf{i}}{\mathbf{Lsin\theta }}}$

The force on the wire will be zero if i = 0 or sinθ = 0
