Question

Recall the behavior of the compass needle as you explored the magnetic field created by the coil. Indicate which two of the following five statements are true. Select one or more: a. It is not possible to decide which end of the coil is a magnetic North when current is flowing through the coil. b. If I always move in the direction indicated by the compass needle, thus following a given field line, my path will trace a loop going around the coil without entering it and returning to my point of departure. c. If I always move in the direction indicated by the compass needle, thus following a given field line, my path will trace a loop going through the inside of the coil and returning to my point of departure. d. As the compass enters one end of the coil, the needle first aligns with the axis of the coil and its orientation reverses as you move the compass along the interior of the coil and exit at the other end. e. As the compass enters one end of the coil, the needle aligns with the axis of the coil and its orientation does not change as you move the compass along the interior of the coil and exit at the other end.
