The figure below shows a section of an overhead power line that is 57.5 m long and carries a current of 2.25 kA. The current is directed to the north. The magnitude of the Earth's magnetic field at this location is 5.30 x 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. WAS 65.0 Ⓡ (a) What is the magnitude of the magnetic force (in N) on the power line? N (b) What is the direction of the magnetic force on the power line? O north (in the same direction as I) O south (in the opposite direction as I) O east (out of the page) O west (into the page) O upward O downward O in the same direction as B
