EC2: A magnet moves through the opening within a closed wire loop, and then comes to rest, relative to the loop. The loop is attached only to a meter that displays the current running through it (and not to any emf device). a. As the magnet is moving relative to the loop, does the meter register a non-zero current? b. When the magnet is at rest relative to the loop, does the meter register a non-zero current? c. What is meant by the statement that magnetism is a "relativistic" effect of electricity?

Expert Solution
Step 1
(a)
As the magnet moves relative to the loop, a changing magnetic flux is produced.
Step 2
This in turn produces EMF and current. Thus, the meter registers a non-zero current.
