Question

A high-voltage power line carries a current of 105 A at a location where the Earth's magnetic field has a magnitude of 0.588 G and points to the north, 74.7° below the horizontal. Calculate the magnitude of the magnetic force exerted on a 253 m length of wire if the current in the wire flows horizontally toward the east Submit Answer Incorrect. Tries 3/16 Previous Tries Calculate the magnitude of the magnetic force exerted on a 253 m length of wire if the current in the wire flows horizontally toward the south. Submit Answer Tries 0/16

Explanation / Answer

A) magnitude of magnetic force = I L B sin theta

= 105 * 253 * 0.588 * 10-4 * sin (90 - 74.7)

= 0.412 N

b) magnitude of magnetic force = I L B sin theta

= 105 * 253 * 0.588 * 10-4 * sin (90 - 74.7)

= 0.412 N
