Basic knowledge of magnets and examples of problems such as breakage, rust, and loss of magnetic strength.

At Niroku Seisakusho, which handles permanent magnets, we are currently offering an introductory material titled "Magnet Trivia You Can Understand in 5 Minutes." It includes basic knowledge such as "Why do magnets stick to iron in the first place?" and the causes of magnetic force reduction. This is recommended for those who want to learn about magnets from scratch! 【Contents (excerpt)】 ■ What is the North Pole? ■ Why do magnets attract iron? ■ Types of magnets ■ Uses of magnets ■ Causes of demagnetization ■ Examples of magnet-related troubles *This material can be viewed via "PDF Download." Please feel free to contact us with any inquiries.

Detailed information

Ferrite magnet It offers the best cost performance. It is brittle but resistant to rust.
Neodymium magnet It is a magnet with the highest magnetic energy among existing magnets. It is prone to rust, so it is treated with nickel plating as a rust prevention measure.
Samacova magnet has a high magnetic energy, second only to neodymium magnets. It is brittle but can be used in high-temperature environments.
Alnico magnets are magnets that are prone to demagnetization but have excellent temperature characteristics. Among magnets, they can be used in the highest temperature environments.
Rubber magnet While the adhesive strength is not very strong, it is ideal for cases where printing is required due to its excellent flexibility in sheet form.
Cap magnet A metal cap is attached to the magnet. There is no magnetic force on the cap surface, but the magnetic force is concentrated on the magnet surface, allowing for a stronger adhesive force than the magnet alone.
