Magnets by Shape

This is a complete list of all magnet shapes

There are Seven basic magnet shapes

A disc magnet is a thin, flat, circular magnet with a uniform thickness, typically resembling a coin or a washer. Its magnetic poles are usually on the two flat, circular faces—one face being the north pole and the other the south pole—creating a magnetic field that is strongest at these surfaces and along the axis perpendicular to them.

A block magnet is a rectangular or cubic magnet with a solid, three-dimensional shape, characterized by its length, width, and height. Typically, the magnetic poles are located on two opposing faces, with the north pole on one face and the south pole on the opposite, creating a magnetic field that is strongest at these surfaces and along the axis between them.

A cube magnet is a three-dimensional magnet shaped like a cube, with all six sides of equal length. It has strong magnetic properties due to its composition and shape. Each face of the cube can exhibit magnetic poles, usually with north and south poles on opposite faces, creating a uniform magnetic field.

A rectangular magnet is a type of block magnet with a rectangular prism shape, defined by its length, width, and height, where at least one dimension differs significantly from the others (unlike a cubic magnet). Its magnetic poles are typically on two opposing rectangular faces, with the north pole on one face and the south pole on the opposite, generating a magnetic field strongest at these surfaces and along the axis perpendicular to them.

A cylinder magnet is a magnet shaped like a solid rod or tube, with a circular cross-section and a height that may be greater than, equal to, or less than its diameter. Its magnetic poles are typically located on the two flat, circular ends, with the north pole on one end and the south pole on the opposite, producing a magnetic field that is strongest at these ends and along the longitudinal axis.

A ring magnet is a three-dimensional magnet shaped like a flat, circular disk with a central hole, resembling a washer or donut. Typically made from materials like neodymium (NdFeB) or ferrite, it has strong magnetic properties. The magnetic poles are usually on the flat faces, with the north pole on one face and the south pole on the opposite, creating a magnetic field along the magnet’s axis. In some cases, it can be radially magnetized, with poles on the inner and outer curved surfaces. Neodymium ring magnets are especially powerful, graded (e.g., N35, N52) for strength, and are often coated (e.g., nickel, epoxy) for corrosion resistance. They are used in applications like electric motors, speakers, magnetic bearings, and jewelry clasps. Sizes vary, with different outer and inner diameters and thicknesses, and their central hole makes them ideal for mounting or applications requiring a pass-through magnetic field.

A countersunk magnet is a magnet, typically made of neodymium (NdFeB) or ferrite, with a flat shape (often disc or rectangular) and one or more countersunk holes. The countersunk hole has a conical taper, allowing a flat-head screw to sit flush with the magnet’s surface for secure mounting. These magnets are usually magnetized through their thickness, with the north pole on one face and the south pole on the opposite, creating a strong magnetic field along the axis. Neodymium countersunk magnets are powerful, graded (e.g., N35, N52) for strength, and often coated (e.g., nickel, epoxy) for corrosion resistance. They are widely used in applications like cabinet closures, tool holders, and fixtures where a flush, screw-mounted magnet is needed. Sizes vary, with different diameters or lengths and hole sizes, and the countersunk feature makes them ideal for easy, non-protrusive installation.
