Product Description


One type of custom magnet is the stepped magnet, also known as a step-shaped magnet or stepped block magnet. These magnets feature a flat surface with a step or series of steps cut into one or both sides of the magnet. This design allows for greater control over the magnetic field, making it ideal for use in precision equipment or machinery.

The stepped magnet is commonly made of neodymium, also known as NdFeB, which is one of the strongest magnetic materials available. By customizing the shape and size of the magnet, its performance can be tailored specifically to the needs of the application. In contrast, standard cylindrical magnets have a uniform magnetic field, which may not be suitable for more complex machinery.

Custom-stepped magnets are also useful in medical equipment and laboratory research. In these applications, precision, and control are critical, and the unique magnetic field properties of the stepped magnet can provide a significant advantage. For example, in magnetic resonance imaging (MRI), stepped magnets can be used to tune the magnetic field to create sharper images with better resolution.

We offer a variety of shapes and sizes, including stepped magnets, trapezoid magnets, countersunk magnets, and so on, to fit specific designs.

Stepped NdFeB Magnet Applications

One example of a custom stepped magnet application is in electric motors, where the stepped shape can increase the efficiency of the motor. By using a stepped magnet, the magnetic field can be focused more precisely on the rotor, which results in less energy loss due to eddy currents. This means that the motor can operate more efficiently, which reduces energy consumption and ultimately saves money.


Another application for stepped magnets is magnetic separators. These industrial machines are used to separate magnetic materials from non-magnetic ones. Stepped neodymium magnets can be used to create a magnetic field that is stronger in some areas than others, which improves the efficiency of the separator.
