Theory about parallel action experiment

I have done an experiment named parallel action experiment, which shows the movement of a test coil in a magnetic field that is not allowed by Lorentz force law. Please see the video

The setup of this experiment is shown in Figure 1. The test coil carries a current that is influenced by the magnetic field B created by the magnet. The test coil, which is plane and perpendicular to its axle of rotation, can turn only in its plane. The video shows, when the current flows, signaled by the blinking of the led, the coil rotates in its plane.
