Neodymium Disc Magnets

Unmatched strength in a compact shape. These magnets have the highest strength-to-size ratio of any magnet, delivering powerful pull force even in tight spaces. Their flat, round shape creates a strong, even pull across surfaces for reliable holding power. However, they may lose magnetic strength at high temperatures. Also known as rare earth magnets.

Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron surfaces. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Magnets


Magnetized Through Thickness	Magnetized Through Diameter

Magnetized Through Thickness—Magnetized from one flat face to the other, these magnets deliver a concentrated magnetic force. They’re best for direct contact with flat surfaces.

Magnetized Through Diameter—Magnetized outward from the center, these magnets generate a circular magnetic field. This makes them best for sensors and motors where rotational symmetry and precise angles are key.

Nickel Plated—With a nickel-plated finish, these magnets stand up to solvents, salt water, and chemicals better than uncoated neodymium. The plating may wear off over time, so these are not recommended for applications with a lot of friction or wear.

Neodymium Rectangle Magnets

Unmatched strength in a compact shape. These magnets have the highest strength-to-size ratio of any magnet, delivering powerful pull force even in tight spaces. Their flat, rectangular shape creates a strong, even pull across surfaces and fits easily into slots or grooves. However, they may lose magnetic strength at high temperatures. Also known as rare earth magnets.

Neodymium Ball Magnets

Magnetized

Thickness

Attract metal from all angles. These magnets create an even magnetic field around the sphere. They’re often used in rotating assemblies and sensor-calibration systems where full magnetic exposure is a must. With the highest strength-to-size ratio of any magnet, these deliver powerful pull force even in tight spaces.

Nonmarring Encased Neodymium Rectangle Magnets

These safeguarded magnets grip surfaces without marking them. The rubber-coated case protects metal housings and control panels from scratches and adds friction for a tight grip. It also shields the magnet from cracks and chips caused by drops and bumps. With the highest strength-to-size ratio of any magnet, these deliver powerful pull force even in tight spaces.

Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Magnets With Unthreaded Hole

Mount with pins, bolts, or rivets. There's no need for threading.

Encased Neodymium Disc Magnets

Powerful performance with built-in durability. A protective case shields these magnets from the elements as well as cracks and chips when handling, mounting, or sweeping them. With the highest strength-to-size ratio of any magnet, these deliver powerful pull force even in tight spaces.

Magnets With Unthreaded Hole

Mount with pins, bolts, or rivets. There's no need for threading.

Nickel-Plated Steel Case—Offers similar corrosion resistance to chrome plating to withstand salt water and chemicals. However, nickel is more likely to wear off over time.

Multipole Neodymium Disc Magnets

Grip thin metal surfaces where standard magnets fail to hold. These magnets have multiple small poles that generate a shallow, concentrated magnetic field only near the surface. This makes them less likely to accidentally stick to nearby objects. They're often used to mount sensors on thin-walled enclosures or control panels. With the highest strength-to-size ratio of any magnet, these deliver powerful pull force even in tight spaces. Also known as Polymagnets®.
