Problem

A straight conductor of length

0.50\,\text{m}

carries a current of

5\,\text{A}

. Only

0.20\,\text{m}

of its length lies inside a uniform magnetic field of

0.30\,\text{T}

, and this portion is perpendicular to the field. What is the magnitude of the magnetic force acting on the conductor while it is in this position? a)

0.60\,\text{N}

0.15\,\text{N}

0.30\,\text{N}

0.75\,\text{N}
