Coil coil – Interaction

In blenders, drills, electric shakers do not have magnets, in their place and performing the same function we find coils, both on the shaft and outside. When an engine of this type is put into operation, there is an electric current in the coils attached to the housing and also in one of the coils fixed on the shaft, where each of them will create a magnetic field in the region. The first two coils have the function of creating a magnetic field in the region where the axis is located. The coil L 4545 123 3 with current attached to the axis will “know” this magnetic field, that is, on it will act the magnetic force, and so it rotates along with the axis.

To understand, we can imagine that each of these coils has only one revolution, that the electric current in the coil attached to the axis is subjected to a pair of magnetic forces and, therefore, makes the rotation of the axis. If there were only this coil, the rotation would not be complete, because the forces would not move the coil when they had the same direction of the magnetic field and that is why there are several coils in the motor shaft instead of one.
