Question

Gather data: Click Reverse to move the magnet down to the bottom. The wire loop should be directly above the magnet, as low as you can drag it.

A. How many magnetic field lines are currently going through the loop?

Answer 1

There are currently zero magnetic field lines going through the loop as the magnet is below the wire loop.

Answer 2

Click Forward and wait until the magnet gets to the top. How many field lines are

passing through the loop now?

Answer 3

As the magnet moves to the top and gets closer to the wire loop, the number of magnetic field lines passing through the loop will increase. It may vary depending on the strength of the magnet, distance from the loop, and other variables.
