How to choose the right ring magnet material?

Hello! Do you have a magnet purchase requirement today? Please, remenber to contact us if you need anything about magnets!

Today, let me talk about "How to choose the right ring magnet?"

Many people often use the word "magnetic ring" as a search key word to find the magnetic ring they need. When they used the magnet, only to find that it is not the kind of magnetic ring they want, do not have the performance they need.

Courage magnet suggests that it is important to know the desired characteristics of the magnetic ring and have the right goals and product solutions before purchasing a magnetic ring, rather than blindly to buy and test.That not only will not solve the problem, it will waste more time and cost.

The main way to know what performance ring magnet need is to see the application.

For example, the motor ring magnet and the ring magnet used in the wire is unlike. The motor generally used at high working temperature, so the ring magnet they used must be resistant to a certain temperature (more than 100℃). When the motor working, the temperature of motor will gradually rise because of rotating friction, so the magnetic ring must have the property of degaussing and avoid performance loss. The magnet have the positive and negative. When used on a motor to provide the magnetic field, it will interacts with the electromagnetic field provided by the motor coil, thereby causing the rotor to rotate.

The appearance is NdFeb ring magnets;

The ring magnet on the wire is not like this, it is non-magnetic. If the non-magnetic magnetic ring is installed on the motor, it will not only not work, but also cause some electronic components of the motor to be damaged. It is used in the place of interference because the non-magnetic magnetic ring belongs to a kind of electronic component that can eliminate EMI (Electromagnetic interference), such as wire, smartphone, computer component, household appliances, etc. It can play an anti-interference role for protecting your electronic products all the time.

Transformer magnetic rings typically use nickel zinc magnetic materials. Nickel zinc magnetic ring is a high conductivity magnetic material with high magnetic permeability and saturation magnetic induction strength. They have good magnetic properties and are suitable for high-frequency applications and magnetic core materials for transformers.

Manganese zinc magnetic rings also exist, but are typically used in applications such as inductors, filters, and magnetic chokes, rather than in transformers.

Our company mainly provides permanent magnet iron rings, such as rare earth neodymium ring magnets, ceramic ring magnets, samarium cobalt ring magnets, and bonded ndfeb ring magnets. If you have samples but are unsure of the material, please provide us with sample pictures to help you confirm.
