Magnet Shapes – Custom Different Shapes of Permanent Magnets

Permanent Magnets are not standard products and they come in all shapes and sizes according to a great variety of applications from customers.

Some are sintered into block or cylinder material and then through different machining methods (as below), they can be made into the right shape and size.

Some are cast into a mold to get the specific magnet shape, but ultimately, they need grinding to achieve final dimensions.

They can be made into bar, rectangle, block, horseshoes, round, rings, donuts, disc, segment, bread, multi-fingered rings or other custom simple or complex shapes.

The shapes of magnets determine how the magnetic field lines are arranged outside of the magnet, which also affects where the magnet can be used.

When it comes to magnet, we will think of horseshoe magnet (also u shaped magnet) immediately. Although in practical application, we hardly see it. It’s still considered the symbol for a magnet and used as teaching tool nowadays.

Segment, arc or bread shape magnets are usually used on different motors because they can be fixed to round rotor or stator.

Every shape of magnets is customized based on their application. If conditions allow, use magnet as simple as possible, for using complex shape magnet will increase a lot of your cost. But when there is no much space for magnet, and you need higher magnetic force, please ask help from us. Our engineer will give you the best solution.
