Experiments with magnets and our surroundings
What do magnetic fields look like?
Two disk magnets, stuck together, about to be slid apart (sometimes
this is the only way to pull two magnets apart!)
Here are some better details of two magnets that are stuck to each other.
You can see how the fields want to line up again, pulling the two magnets into alignment.
This shows the magnetic field strength around the two magnets. Interesting plot.
