Neodymium magnets generate stronger magnetic fields than ferrite and aluminium-nickel-cobalt magnets. They are referred to as strong permanent magnets and are classified as neodymium and samarium-cobalt. Rare earth neodymium magnets were developed after samarium-cobalt magnets and are brittle and corrode easily, requiring various anti-rust coatings. The most economical and durable rare-earth magnet is the neodymium magnets wholesale, primarily produced in China.
Segmented permanent magnets designed for motors, generators, and AC generators are arc magnets (magnetic tiles), typically used for rotors and stators. Several arc magnets with different inner diameters and polarities can be assembled into a multi-stage magnetic ring. In a motor, magnetic rings with alternating polarity on the inner diameter rotate near the copper coil. We are a leading manufacturer of arc segment neodymium magnets. We not only offer a selection of neodymium segmented magnets in specific sizes, but we can also produce custom segmented permanent magnets based on orders.
Rectangular magnets with a high length-to-width ratio are called rectangular magnets. Square rectangular magnets are susceptible to fracture due to external pressure. Square magnetic poles mainly exist in aluminium-nickel-cobalt and ferrite. Our rectangular magnets for sale can provide greater magnetic force and are only used for heavy grips.
Special circular magnets with different axial magnetizations at both ends are called cone (cone-shaped) magnets. The large surface is usually described as the base of a cone-shaped permanent magnet. The magnetic field generated by the top is more concentrated and stronger than that of the base. Cone neodymium magnets are made of neodymium iron boron alloy and have a strong magnetic force. Some sizes are offered as standard neodymium cone magnets to magnet distributors worldwide.
Permanent magnets with countersunk holes are called countersunk magnets, which can be installed with screws. You can screw them onto non-metal surfaces, so they are also called screw-on and installable magnets. Our China countersunk magnet can be used for circular magnets, block magnets, arc magnets, channel magnets, and pot magnets. The neodymium countersunk ring magnet is the most popular and widely used screw magnet.
This type of permanent magnet has the same length, width, and height, is surrounded by six equal square faces, and any two adjacent faces are at right angles, commonly known as cubic magnets, made of neodymium magnetic material. This special neodymium block magnet is widely popular for its amazing magnetic force and is used in numerous applications. Our neodymium cube magnets for sale are used as medical magnets, sensor magnets, robot magnets, holding magnets, and toy magnets.
