A sinusoidally oscillating current I$($t$)$ with an amplitude of

$5\mathrm{.}55$ A and a frequency of $359$ cycles per second is carried by

a long, straight wire. A rectangular loop of copper wire with

dimensions b $=27\mathrm{.}2$ cm by c $=12\mathrm{.}2$ cm is located

a $=30\mathrm{.}2$ cm from the straight wire, and is coplanar with it$.$
