GN58 Pot Magnet, Through Bore, Steel Housing
A pot magnet consists of a steel shell containing a powerful magnet. This steel pot directs the magnetic field lines downward to the contact surface. This causes the magnetic force to be concentrated at the contact surface and therefore increases the strength of the magnet.
This strong adhesive force occurs only on direct contact with the counterpart. A pot magnet is not suitable for attraction over distance. For the best adhesive force the contact surface should ideally be a thick, smooth and unpainted surface.
To ensure that the magnetic properties are not impaired, the fixing screws must be made of non-magnetic material.
For easier handling and/or to avoid demagnetisation, these magnets have an iron plate on their adhesive surface.
With bore for fixing.
