Question
A current-carrying wire in the field of a horseshoe magnet experiences a force as shown in the two cases below. In each case, the north pole of the horseshoe magnet is the rightmost pole. The force arrow shown in each case represents the force on the current-carrying wire by the magnet. (a)In each case, what is the direction of the force ON the magnet BY the current-carrying wire? The force ON the magnet BY the wire is in the direction of the south pole in the left-hand picture and in the direction of the north pole in the right-hand picture. downward in the left-hand picture and upward in the right-hand picture. out of the page in the left-hand picture and into the page in the right-hand picture. into the page in the left-hand picture and out of the page in the right-hand picture. in the direction of the north pole in the left-hand picture and in the direction of the south pole in the right-hand picture. (b)Which is stronger, the force on the wire by the magnet, or the force on the magnet by the wire? The force on the wire by the magnet is stronger. The force on the magnet by the wire is stronger. The two forces are equally strong.Explanation / Answer
Downward in the left-hand picture and upward in the right-hand picture
The two forces are equally strong
