A horizontal compass is held on the surface of the Earth directly over a buried powerline with a current of 200 A heading due south. The compass is 5 m above the powerline. In what direction does the compass needle point at this location andwhat is the magnitude of the total magnetic field at this point? Assume the horizontal component of the Earth’s field at this point is 0.45 x 10‐4 T and is directed due north.

Lab Scenario: You don't have a current meter in your underequipped lab. So you make one out of a compass. The wire you want to measure the current in is aligned with the North South line. You place your compass directly under the wire at a distance of 10cm from the wire. With no current flowing, the compass needle points due north. When you turn on the current, the compass needle points 5 degrees west of north. You now have...

A circular coil of wires (N = 10 turns, R = 3.5 cm) is oriented so that the axis of the coil runs east to west. A compass pointing north sits a distance of d = 12 cm from the center of the coil and lies on the axis of the coil. The horizontal component of the Earth’s magnetic field at this location has a magnitude of 2.5×10−5 T. When a current is turned on the compass needle now points...

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...

Two hikers are reading a compass under an overhead transmission line that is 5.30 m above the ground and carries a current of 790 A in a horizontal direction from north to south. Find the direction of the magnetic field at a point on the ground directly under the conductor. I already know the answer so I just need a full explanation why, I did the right-hand rule but its wrong so how?
