Third pole of repelling magnets also shown on a crt

Sorry, could't remember the video I mentioned previously. I found a second video that demonstrates this quite nicely.

Magnetic dipolar attraction:

Magnetic dipolar repulsion:

Magnetic dipolar repulsion when same poles are brought very close:

Note: Ellipsoid pattern changes to a circle due to condensation. Magnets are not strong enough to produce a black circle on the crt and in between the poles circlular pattern appears colored and much more magnified by the crt. In a ferrocell the circle appears much smaller and black due to the greater sensitivity and spatial resolution of the ferrocell.
