Question

Consider a straight wire of length $ l $ carrying a current $ I $ placed in a uniform magnetic field $ \vec{B} $. Which of the following expressions correctly represents the magnetic force $ \vec{F} $ acting on the wire?

Accepted Answer

$ \vec{F} = I l \times \vec{B} $

Answer

$ \vec{F} = I l \cdot \vec{B} $

Answer

$ \vec{F} = I \vec{B} \times l $

Answer

$ \vec{F} = I \vec{B} \cdot l $
