Problem

A straight

10\,\text{cm}

length of wire carries a steady

2.0\,\text{A}

current toward the south. This segment lies in a uniform

0.30\,\text{T}

magnetic field that points vertically downward. Determine the magnitude of the magnetic force on the wire segment and indicate its direction.
