Problem

A straight conductor of length

0.50\,\text{m}

is placed in a uniform magnetic field of magnitude

0.30\,\text{T}

directed towards the east. A current of

4\,\text{A}

flows through the conductor vertically downward. The direction of the magnetic force on the conductor is a)

\text{towards east}

\text{towards west}

\text{towards south}

\text{towards north}
