Question

Horizontal electric power lines supported by vertical poles can carry large currents. Assume that Earth’s magnetic field runs parallel to the surface of the ground from south to north with a magnitude of 0.50×10^−4 T and that the supporting poles are 34 m apart.

1)Find the magnitude of the force that Earth’s magnetic field exerts on a 34-m segment of wire carrying 75 A if the current runs from north to south. (Express your answer to two significant figures.)

2)Find the magnitude and direction of the force that Earth’s magnetic field exerts on a 34-m segment of wire carrying 75 A if the current runs from east to west. (Express your answer to two significant figures.)

3)Find the magnitude and direction of the force that Earth’s magnetic field exerts on a 34 m segment of wire carrying 75 A if the current runs toward the northeast making an angle of 30∘ north of east. (Express your answer to two significant figures.)
