At a site where the Earth's magnetic field has a magnitude of 0.45 gauss (where 1 gauss = 1.00 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
magnitude | in N |
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 |
