A Wire Along The $z$ -Axis Carries a Current Of $4.9 \mathrm {~A}$

Short Answer

A wire along the $z$ -axis carries a current of $4.9 \mathrm {~A}$ in the $+ z$ direction. Find the magnitude and direction of the force exerted on a $3.3 - \mathrm { cm }$ long length of this wire by a uniform magnetic field pointing in the $- x$ direction having a magnitude $0.43 \mathrm {~T}$ .
