At a site where the Earth's magnetic field has a magnitude of 0.52 gauss (where 1 gauss = 1.00 × 104 T) and points to the north, 68° below the horizontal, a high-voltage power line 210 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 direction × What quantities determine the magnitude of the magnetic force acting on a current carrying wire in a magnetic field? N -Select- What is the right-hand rule for magnetic forces? at What angle must the magnetic force make with the magnetic field? With the current?" measured below the horizontal (b) horizontally toward the west magnitude direction N -Select-at ⚫ measured below the horizontal
