Problem

A wire lying along the

y

-axis from

y=0

y=1\,\text{m}

carries a current of

2\,\text{mA}

in the negative

y

-direction. The wire lies in a non-uniform magnetic field given by

\mathbf{B}=(0.3\,\text{T/m})y\hat{\mathbf{i}}+(0.4\,\text{T/m})y\hat{\mathbf{j}}

. The magnetic force on the entire wire is
