Textbook Question
Chapter 7.2, Problem 2bT
B. Suppose you hold a magnetic compass near a current-carrying wire as shown.
(A magnetic compass is a magnet that can rotate freely.) The face of the compass is parallel to the tabletop.
1. Predict the orientation of the compass needle when the circuit is complete. Sketch a diagram that shows the wire, the direction of the current through it, the direction of the magnetic field directly below the wire, and the predicted orientation of the compass needle.
2. Check your answer. If the deflection of the needle is not what you predicted, resolve the discrepancy. (Hint: Is there more than one magnetic field affecting the compass?)
