Title:
RING-SHAPED PERMANENT MAGNET
Document Type and Number:
WIPO Patent Application WO/2022/265260
Kind Code:
A1
Abstract:
The present invention relates to a ring-shaped permanent magnet. The magnetic field of the permanent magnet has both a rotational direction value and an axial direction value. When the magnet rotates, the magnetic field is spherically symmetrical about the rotation axis. Therefore, when the ring-shaped permanent magnets are facing each other, a rotation force is generated due to the repulsive force between the magnetic fields from the two permanent magnets.
