A straight $2\mathrm{.}7$ m wire carries a typical household current of $1\mathrm{.}5$ A

$($in one direction$)$ at a location where the earth's magnetic field is $0\mathrm{.}55$ gauss from south to north.

Part A

Find the direction of the force that our planet's magnetic field exerts on this wire if it is oriented so that the current in it is running from west to east.

The force is directed upward. The force is directed downward. The force is directed from east to west. There is no force exerted on the wire.
