Smaller Acrylic Compass Motor at Full Speed

The powerful magnets form a compass with about 2 millinewton meters of torque in Earth's magnetic field.
A small electric motor turns the magnets so they are not pointing north.
The magnets keep trying to point north and the electric motor keeps turning them so the acrylic armature, free to rotate, turns under the torque of the magnets against Earth's magnetic field.

The motor is shown running as fast as it can run.

Stay tuned:)
