When you think of magnets, you may picture the typical U-shaped magnets that secure papers to the refrigerator. But do you know what other types of magnets special features they have? An example of an interesting type is the diametrically magnetized disc magnet.
Diametrically magnetised disc magnets are small, circular magnets that are magnetised in a unique way. Unlike normal magnets which have only two poles, one north and one south, radial magnets are magnetized along the diameter. This expresses one side north, the other south.
It is this unique way of magnetising that gives these magnets some neat properties. That’s because they can be more powerful than comparable magnets of the same size, for example. That’s because their magnetic field fans out wider along the circumference, making it easier for them to stick to other magnetic things.
You can find these magnets in lots of things we use in technology. A typical use is in magnetic sensors, since their special characteristics can sense changes in a magnetic field. This is significant in devices such as compasses, where obtaining accurate readings is essential.

They are present in electric motors and generators, contributing to their high magnetic field levels to drive motion. Many contemporary electric cars use these magnets in their motors to power the vehicle.

Applications for these magnets vary widely. They can be found in everyday objects like speakers, headphones and computer hard drives. In medicine, MRI machines produce detailed pictures of the body by using magnets. They are also employed in factories for machinery and equipment.

A particularly fascinating application of these magnets is in the field of magnetic levitation. Magnets can push against one another to make objects float in the air with nothing touching them. This technology is found in high-speed trains and certain amusement park rides.
