Magnetic coupling is a coupling that transfers torque from one
shaft, but using a magnetic field rather than a physical mechanical
connection.
Magnetic couplings are most often used for liquid pumps and
propeller systems, since a static, physical barrier can be placed
between the two shafts to separate the fluid from the motor
operating in air. Magnetic couplings preclude the use of shaft
seals, which eventually wear out and fail from the sliding of two
surfaces against each another. Magnetic couplings are also used for
ease of maintenance on systems that typically require precision
alignment, when physical shaft couplings are used, since they allow
a greater off axis error between the motor and driven shaft.

4. How does magnetic coupling work?
Production process
Manuafacturing Process and Magnetization
1. With dry process can produce isotropic & anisotropic magnets,
the tool can be changed and developed easily.
2. With wet process only can produce anisotropic magnets,it is
complicated to change the tool and the tooling charge is high.
3. Isotropic ferrite magnets can be magnetized in any direction.
4. Anisotropic ferrite magnets are all oriented in the
manufacturing direction, and can be magnetized in the direction of
orientation.
