Question
The free electrons in a conducting wire are in constant thermal motion. If such a wire, carrying no current, is placed in a magnetic field, is there a magnetic force on each electrons? Is there a magnetic force on the wire?

Solution
Yes,
each electron experiences a force. But since the motion is random, the net force on collective electrons is zero.
