A permanent magnet is a material that produces a persistent magnetic field without external power, used in moving coil mechanisms for precise motion control.
A permanent magnet is a ferromagnetic or ferrimagnetic material that retains its magnetic properties after being magnetized, creating a stable magnetic field. In moving coil mechanisms, it provides the static magnetic field that interacts with the current-carrying coil to generate precise linear or rotational motion through Lorentz force principles. These magnets are engineered for high coercivity, remanence, and thermal stability to maintain performance in industrial applications.

NdFeB magnets offer higher magnetic strength and are cost-effective but have lower temperature resistance (typically up to 150°C). SmCo magnets provide better thermal stability (up to 350°C) and corrosion resistance but are more expensive and have slightly lower magnetic strength.
Degradation occurs through thermal demagnetization (exceeding Curie temperature), corrosion (especially in NdFeB), mechanical shock, and exposure to strong opposing magnetic fields. Proper material selection, coatings, and operating within specified parameters minimize degradation.
Yes, magnets can be engineered in custom shapes (arcs, blocks, rings), magnetic orientations (radial, axial), and grades to optimize magnetic field distribution, force output, and integration with coil and mechanical structures.
