Neodymium cone magnets, also known as NdFeB magnets, are made from a mixture of neodymium, iron, and boron alloys. These magnets are the most powerful permanent magnets commercially available, with high magnetic field strength. The cone-shaped structure of these magnets allows for a directional magnetic field, making them ideal for various applications. Neodymium cone magnets come in different sizes and strengths, ranging from small sizes for portable devices to large sizes for heavy machinery.

Cone shaped magnet is a special round magnet with different diameters of the two magnetizing surfaces, all cone magnets in this category are made of rare earth neodymium, and are known as rare earth cone magnets or neodymium (NdFeB) cone magnets. Cone-shaped neodymium magnets are custom magnets, we only list several cone shape neodymium magnets which are best sellers for most of the magnet distributors, welcome you to contact us for other custom cone-shaped bulk neodymium magnets.


Types of Neodymium Cone Magnets

Neodymium Cone Magnet Features&Characteristics

Neodymium cone magnets are special axially magnetized disc magnets, cone magnets of neodymium are not rustproof, surface treatment needed from them. The power of neodymium cone magnets are range from N35 to N52. The magnetic line of force of the conical(cone) shaped neodymium magnet is bound on the smaller magnetic pole, which makes the neodymium cone magnet have very high magnetic adhesion.

Neodymium Cone Magnet Application

Neodymium Cone Magnets are a specialized type of magnet that has a conical shape, which makes them ideal for applications where a traditional magnet won't fit. They are made of neodymium, iron, and boron, which are combined using a process called sintering to create a material that is exceptionally strong and magnetic. Neodymium Cone Magnets are used in a variety of applications due to their unique shape and strength. Here are some of the most common applications for Neodymium Cone Magnets:

1) Magnetic Holding - Neodymium Cone Magnets are often used for magnetic holding applications due to their strength and unique shape. They can hold onto ferrous materials with great force, making them ideal for holding and securing metal objects. They are often used in industrial and manufacturing applications, where magnetism is needed to hold pieces in place during assembly or welding.

2) Automotive - Neodymium Cone Magnets are commonly used in the automotive industry due to their strength and durability. They can be used to secure parts in place, and can also be used as sensors in various automotive systems. For example, they can be used in speed sensors to detect the rotational speed of the wheels.

3) Sensors - Neodymium Cone Magnets are often used as sensors in a wide range of applications. They can be used to detect the movement of gears, the position of a door, or the presence of ferrous materials. They are often used in security systems, elevator shafts, and manufacturing facilities.

4) Medical Equipment - Neodymium Cone Magnets are used in a variety of medical devices due to their strong magnetic fields. For example, they can be used in MRI machines to create images of the human body. They can also be used in devices like insulin pumps or pacemakers, which rely on magnetic sensors to regulate their operations.

5) Audio Transducers - Neodymium Cone Magnets are also used in audio transducers, such as speakers and headphones. They provide a strong and stable magnetic field that can accurately reproduce sound. They are often used in high-end audio equipment, where clarity and accuracy are important.

In conclusion, Neodymium Cone Magnets are an ideal choice for many applications due to their strength and unique shape. They can be used in a variety of industrial, automotive, medical, and audio applications, and provide reliable and accurate performance. If you're looking for a magnet for your next project, consider a Neodymium Cone Magnet - it just may be the perfect solution for your needs.
