Generally our searching magnet is composed of an outer round cup steel and a ring neodymium
magnets inside with a hole in the centre or a disc magnets, which
has been broadly applied into fishing application.
The inner magnet of cup magnets could form a special magnetic
circle with the the housing steel when putting it on an ferrous
material surface, which is much be strongger than the the magnet
self can do. At the same time, the outer cup steel can prevent the
inside magnets from damaged or crushed. In some of applications, it
can be filled with Epoxy between the cup steel and the magnet to
stop some iron dust adsorbed into the gap.
Please find more specifications as showing as bellows. Also your
special designs could be avaiable for us.
