Problem

A straight conductor of length

0.40\,\text{m}

carries a current of

10\,\text{A}

at right angles to a uniform magnetic field. If a force of

0.20\,\text{N}

is to act on the conductor, what is the minimum magnetic induction required? a)

0.50\,\text{T}

0.02\,\text{T}

0.05\,\text{T}

5.0\,\text{T}
