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 38 m apart.

Find the magnitude and direction of the force that Earth’s magnetic field exerts on a 38 m segment of wire carrying 95 A if the current runs toward the northeast making an angle of 30∘∘ north of east. (Express your answer to two significant figures.)

If two wires carry current next to each other, they will exert a force on each other. The force is caused by magnetic fields. One current creates a magnetic field, and this field exerts a force on the other current. The magnitude of the field created by a long, straight current-carrying wire is given by Equation 1 below; B= (μ0i)/(2πr) where i is the current and r is the distance from the wire. The magnitude of the force exerted on...
