010 How did those electrons slip through the magnetic shield (at 00:21) ?

The force experienced by a moving charge is dependent on the angle between directions of v and B. (F = qvBsinθ)

This implies that a moving charge experiences zero force if it is moving along the magnetic field.

In this video, it was shown that the electrons which were headed directly into the pole of the magnet suffered no deflection, while the electrons which were headed around the hole were deflected away.

We are lucky that the Earth’s magnetic field is not oriented with its pole pointing directly at the Sun. If not, we would be defenseless against the solar flare.
