Problem

A straight

8.0\,\text{cm}

length of wire is entirely within a uniform magnetic field of magnitude

0.75\,\text{T}

. The wire makes an angle of

30^{\circ}

with the direction of the field. If the magnetic force on the wire has magnitude

0.15\,\text{N}

, determine the current in the wire.
