Versatile Applications
The ring-shaped design (doughnut shape) allows for unique mounting and mechanical integration possibilities:
-
Industrial Engineering: Ideal for hall effect sensors, motor assemblies, and magnetic couplings.
-
DIY & Cabinetry: Use with a screw or bolt through the center for ultra-strong hidden latches and mounting points.
-
Scientific Research: Perfect for physics experiments involving magnetic fields and torque.
-
Crafting & Jewelry: High-strength magnets for heavy-duty clasps or magnetic levitation displays.
⚠️ Safety & Handling
Neodymium magnets are not toys. Due to the high-force of Grade N52 material:
-
Pinch Hazard: Can cause injury if skin gets trapped between two magnets.
-
Fragility: Neodymium is a brittle ceramic; magnets may shatter if allowed to snap together.
-
Electronics: Keep away from pacemakers, credit cards, and sensitive electronic storage.
