This demonstration illustrated the field waves around the "poles" of the magnet.
From this picture we found out that magnetic field lines come radiate, without intersecting, from one side of the pole into the other side of the pole.
We indicated the direction of the compass' point in several different locations around the magnet. From these lines, we found out that magnetic field lines go from the north pole into the south pole. So, a compass will point in the direction of the magnetic field lines.
Experiment #2 Magnetic Field, Force, and Velocity
In this demonstration, we used a rod, rails, and a power supply and predicted the directed the rod would roll.
