At a site where the Earth's magnetic field has a magnitude of 0.45 gauss (where 1 gauss = 1.00 Image for At a site where the Earth's magnetic field has a magnitude of 0.45 gauss (where 1 gauss = 1.00 multiply. gif 10 10-4 T) and points to the north, 68? below the horizontal, a high-voltage power line 167 m in length carries a current of 120 A. Determine the magnitude and direction of the magnetic force exerted on this wire, if the orientation of the wire and hence the current is as follows.

(a) horizontally toward the south

direction 2---Select---northsoutheastwest at in ? measured below the horizontal

(b) horizontally toward the west

magnitude in N
direction ---Select---northsoutheastwest at in ? measured below the horizontal
