In Figure 24.15 we see a magnet exerting a force on a current-carrying wire. Does a current-carrying wire exert a force on a magnet? Why or why not?
The figure above shows wire loop with current I in the direction shown: Does the loop exert magnetic force on itself? Why or why not? Yes, because the current generates magnetic field, which exerts magnetic force on the current in the loop. Yes, because opposite sides of the loop act like parallel wires: No; because force is defined as an interaction between two objects, so no object can exert force on itself: No, because the current forms closed loop;
'Current flows to the right through the wire shown in the picture below: _ bar magnet is held near the wire so that the south pole of the magnet faces the wire: What can we say about the force exerted on the wire by the magnet? The magnet exerts = force on the wire that points into the page The magnet exerts an upward force on the wire The magnet does not exert a force on the wire The magnet exerts . downward force on the wire The magnet exerts . force on the wire that points out of the page'
