Neodymium cylinder/rod magnets are long and circular, and their length is often longer than their diameter. They can generate larger magnetic fields, sometimes up to 3 times stronger than thinner neodymium disc magnets of equal diameter.
Neodymium cylindrical magnets are found in:
- Medical equipment
- Read switches
- Holding applications
Neodymium ring magnets are like neodymium disc magnets, but a neodymium ring magnet will have a straight-sided hole through the center. You can find them in many everyday appliances such as vacuum cleaners, generators, and rotor shafts.
Neodymium ring magnets are also widely used in producing sound equipment, especially speakers.
Although ferrite magnets were the go-to type for application of this type, manufacturers now use neodymium magnets since they can produce high-quality sound with a smaller size.
Neodymium ring magnets are commonly used in:
- Sound equipment
- Scientific Experiments
- Several other applications
Ring with Countersunk Holes
These are often smaller and thicker than neodymium ring magnets. However, neodymium ring magnets with countersunk holes can take screws through the hole in the center. With this hole, you can screw them to wood, metal, and plastic items.
The hole on these neodymium magnets being countersunk holes, the head of a screw will set right into the hole, not protruding at the top. Neodymium ring magnets with countersunk holes are used in
- Industrial mechanical equipment
- Industrial assembly
Neodymium arc magnets are probably the least popular shape of neodymium magnets since they have a specialized application.
While they are used in magnetic flywheel assemblies, you commonly find them in rotors and stators. Here’s the list of their applications:
- Motor field
- DC motors, Rotors, and Stators
- Electric car
- Car motor
- Car drive motor
- Electric motor, generator
- DC motor
- Electric vehicle motor,
- Motorcycle motor
- Compressor motor
- Electrical tools
- Permanent neodymium magnet DC motor
Neodymium magnet balls are small; they can be as small as 1mm, and as big as 2 inches.
In most instances, neodymium magnet balls are designed as recreational and stress-relieving objects. Besides being used as toys, you can use them to construct miniature or prototype buildings and hold paper against metal or magnetic board.
Due to specific reasons, some applications of neodymium magnet balls and spheres have been banned in some countries.
Illegal uses: several countries, including Canada and New Zealand, have banned using neodymium magnet balls as toys for children. However, they are still available for use in offices and schools.
Jewelry: magnetic balls and spheres have also been used in jewelry to make clasps or form parts of authentic jewelry.
Neodymium Tube/Block Magnets with Countersunk Holes
You can use neodymium magnets with countersunk holes for mounting, holding, lifting, and positioning furniture, items, door latches, and frames.
The magnetic force of neodymium magnets with countersunk holes is focused on the working surface. So the working surface is significantly stronger than an individual neodymium magnet.
To make a neodymium magnet with a countersunk hole:
- Drill a countersunk hole on the base of round, square, column, ring, and tile neodymium magnets, and use them with screws.
Neodymium Irregular Magnets
Neodymium irregular magnets are produced not to fit categorically into any of the standard shapes of neodymium magnets, including balls, rings, arcs, spheres, discs, and blocks.
Neodymium irregularly shaped magnets include those with countersunk holes, arc, and special-shaped neodymium magnets. They are very efficient and can function in electrical equipment. They are also ideal for being fitted into metal, plastics, rubber, and other durable materials.
Neodymium Thin-type Magnets
Neodymium thin-type magnets are used in several consumer products, such as earphones, to produce sound. Usually, it is zinc plated. Here’s how it works:
Fix the enameled coil on the diaphragm, and place a neodymium magnet underneath. When the electric signal passes through the enameled wire, it will generate a magnetic field of different strengths.
Because the permanent neodymium magnet is fixed, the enameled coil drives the diaphragm to vibrate and becomes music to your ears.
Neodymium Mini magnet
These are little bits of neodymium magnets that are used in everyday consumer products. You can use them in:
- Lipstick covers: modern lipstick and other cosmetic cases now have two pieces of neodymium magnets to hold their lids in place.
- Smartphone: while it is true that neodymium magnets will negatively affect smartphones, certain parts of phones require neodymium mini magnets to work. They include the speaker, camera, and vibration module.
- Jewelry boxes: stores use magnetic jewelry boxes to store, transport, and display jewelry. If adapted to a product, a magnetic jewelry box may ensure that the product remains in its position even when knocked.
- Magnetic toys: tiny pieces of magnetic balls that stick together while moving them around to form different shapes and patterns.
