The figure below shows a section of an overhead power line that is 56.5 m long and carries a current of 2.15 kA. The current is directed to the north. The magnitude of the Earth's magnetic field at this location is 5.50 × 10-5 T. The field has a northward component and a downward component, so that it makes an angle of 65.0° with the power line. 65.0° (a) What is the magnitude of the magnetic force (in N) on the power line? 5.6
