Electromagnetism: Magnetic force on wire carrying current
January 22nd, 2023
Part 1
A high-voltage power line carries a current of 120 A at a location where the Earth’s magnetic field has a magnitude of 0.583 G and points to the north, 70.8° below the horizontal. Calculate the magnitude of the magnetic force exerted on a 258 m length of wire if the current in the wire flows horizontally toward the east.
Part 2
Calculate the magnitude of the magnetic force exerted on a 258 m length of wire if the current in the wire flows horizontally toward the south.
