Applications of Neodymium Iron Boron Step Magnets and 5 Common Shape Types

Applications and 5 Common Shapes of Neodymium Step Magnets

Have you ever seen step-shaped trapezoidal magnets? In fact, this type of magnet is quite popular. Primarily made from neodymium iron boron material, it finds applications across various fields. However, its manufacturing process is more complex than conventional magnets. Below is a detailed introduction to this magnet.

Basic Definition of Neodymium Step Magnets:

Neodymium step magnets typically refer to neodymium magnets featuring varying surface heights, resembling staircases in shape. Many customers also call them convex magnets or tapered magnets. We can simply understand them as two magnets of different diameters or widths stacked together.

Neodymium step magnets come in various shapes, each designed to meet specific application requirements. Below are introductions to several common types of neodymium step magnets.

1. Circular Step Neodymium Magnet

This is one of the most common step-shaped magnets, featuring uniform circular outer edges. One end face (typically the axial end) is designed with a step-like protrusion, usually positioned centrally. Magnetic properties are typically recommended at N38 grade or higher.

2. Square Step Rare Earth Neodymium Magnet

Square stepped magnets feature four straight edges and a stepped structure with a square base. Their right-angled design inherently prevents rotation. 3. Short-Shaped Stepped Neodymium Magnets

Rectangular stepped neodymium magnets have a rectangular shape with a regular outline. Based on their rectangular form, one or multiple sides incorporate a stepped structure. The height and width of the steps can be customized according to specific applications.

4. Ring-Shaped Stepped Neodymium Magnets

Ring-shaped stepped neodymium magnets are permanent magnets with a ring structure and stepped surface profile, equivalent to a hole machined into a circular stepped magnet. They are particularly suitable for applications requiring rotation around an axis or passage through an axis.

5. Semi-Circular Stepped Magnets

Semi-circular stepped magnets are neodymium permanent magnets featuring a semi-circular shape with a stepped structure. They can be considered half of a circular stepped magnet. Their unique stepped design enhances magnetic stability and positioning accuracy within specific installation spaces.

The above outlines the definition of stepped magnets and introduces five common shapes. The primary purpose of stepped magnets is to provide more precise mounting positioning and enhance magnetic field concentration. The stepped design enables magnets to deliver stable magnetic fields within more limited spaces while improving the fitting accuracy between magnets and other components. They are widely used in magnetic connection devices.
