Choose from a wide selection of neodymium rare earth magnets and ferrite magnets for the most demanding science, engineering & industrial applications.
Our on-line magnet supplies store consists largely of neodymium rare earth magnets with 125+ sizes of discs, cylinders (rods), blocks (rectangles), squares, cubes and rings. Their uses vary from tripping sensors, holding or lifting objects and even levitation. All of our rare earth permanent magnets are magnetized through their thickness; we do not offer diametrically magnetized magnets.

Ferrite magnets are weaker but more economical. They are particularly good for building magnetic sweepers, among other things, where overall size is important. Our ferrite ceramic magnets come mainly in blocks along with a limited range of discs. Most of the ferrite magnets, like the permanent rare earth magnets, are magnetized through their thickness.
We also supply ferrite bar magnets specifically for educational use. These differ from our other permanent magnets in having their poles at each end & are painted red & blue and stamped "N" & "S" respectively.
These bar magnets are relatively weak and are intended for use with compasses and iron filings to show the shape of magnetic fields similar to that of Earth. They are also ideal for simple demonstrations of attraction and repulsion.

The presence of magnetic fields can be shown in several ways. The simplest are iron filings & compasses which work best with our ferrite bar magnets.
For the more sophisticated or adventurous user, try the magnaprobe which has a gimbal mounted alnico bar magnet that moves in 3D space in response to a magnetic field.
