How to Separate Strong Magnets - KJ Magnetics

Neodymium magnets pull towards each other with a strong force. If you try pulling two magnets directly apart, you need quite a bit of force to pull them apart. To separate one magnet from another, you'll need to pull with a force equal to the listed Pull Force Case 1 number. This can be difficult if the magnet is strong, or if there isn't much ...

Superconducting magnets for magnetic density separation:

Compared to these magnets, superconductors can generate a stronger magnetic field, increasing the upwards force. This allows the separation of dense particles. Another advantage that comes with the stronger magnetic field is that a lower concentration of magnetic nanoparticles in the fluid can be used while maintaining a strong upwards force.
