Round magnets are products used to stick items to magnetic objects made of ferrous metals. Besides sticking objects together, they are also used for applications such as magnetism testing and in parts requiring magnetic attraction. Magnets are available in types such as neodymium, ferrite, cobalt and alnico. The magnetic force of neodymium magnets is one of the strongest among the available magnet products. Neodymium magnets are used in a wide range of applications. Ferrite magnets have a weak magnetic force but relatively high retentivity. Cobalt magnets are officially known as samarium-cobalt magnets. They are known for their resistance to rust and high temperatures. Alnico magnets have superior temperature resistance properties and outstanding mechanical strength. The high retentivity of industrial magnets enables even small models to emit powerful magnetic fields. Using a magnet at temperatures above its maximum operating temperature creates the risk of weakening its magnetic force.

FAQ Magnets - Round
- Question: What is the strongest type of round magnet?
- Answer: The strongest type of round magnet is the neodymium magnet and they are available in a variety of shapes, including rings, cylindrical, rectangle, square and circle with countersunk hole that can be easily mounted onto a surface using a screw. These magnets are known for their extreme strength, compact size, and high coercive force, making them suitable for a wide range of applications especially in factory automation.
- Question: What are cobalt magnets known for?
- Answer: Samarium–cobalt (SmCo) magnets are widely used in various industries, including automotive, medical, industrial manufacturing and semiconductor due to their exceptional magnetic properties:
1. High strength, comparable to neodymium magnets
2. Excellent temperature stability, maintaining their magnetic properties up to about 300°C
3. High resistance to corrosion and oxidation, often not requiring surface treatments.
4. High resistance to demagnetization, making them ideal for applications where magnetic stability is critical. - Question: Can high temperatures affect magnets?
- Answer: High temperatures can significantly affect magnets. When a magnet is exposed to high temperatures the magnetic strength and field weaken. On the other hand, exposing a magnet to colder temperatures increases its magnetism. However, it's important to note that all magnets have a maximum operating temperature, and if this is exceeded, they can experience irreversible losses in performance.
For instance, standard grade neodymium magnets have a maximum operating temperature of 80 °C if you want to use the neodymium magnets over 80 °C we recommend the Heat-resistant grade of Neodymium Magnets, that have a maximum operating temperature150° Therefore, it's essential to consider the temperature effects when using magnets in various applications. - Question: What should be considered when choosing a round magnet?
- Answer: When choosing a round magnet, several factors should be considered Here are the key considerations:
1. Application and Requirements: Understand the purpose and specific needs, for example, the required magnetic strength, size, and shape.
2. Environmental and Temperature Conditions: Consider whether the magnet will be exposed to the temperature range of the application or harsh environmental conditions, for example, standard grade neodymium magnets have a maximum operating temperature of 80 °C
3. Material Type, Size, and Shape: Consider the material type (e.g. Neodymium magnets and Heat-resistant Neodymium Magnets), size, and shape that appropriate to set up in your application
4. Safety Considerations: Consider any safety concerns, especially with strong magnets, to prevent accidents or damage to equipment in the system
By carefully considering these factors, the right round magnet can be selected to meet the project's needs effectively and safely. - Question: Are there special precautions for handling strong magnets?
- Answer: When handling strong magnets, several special precautions should be observed. Here are some of the key precautions include:
1. Keep Distance and Use Caution: Magnets should be kept at a safe distance from metals, steel, and other magnets to avoid immediate impact and prevent magnets from snapping or slamming together, which can cause injuries.
2. Wear Protective Gear: It is recommended to wear eye protection, as magnets, especially neodymium and samarium cobalt, are very hard and brittle and can chip
3. Keep Away from Sensitive Devices: Magnets can affect pacemakers, implanted medical devices, electronic devices. Therefore, they should be kept away from these devices to avoid deactivation or damage
4. Dispose of Carefully: Magnets should be disposed of carefully and in accordance with the relevant guidelines to prevent any potential hazards
