Q: How to choose the right permanent magnet?

There are different magnetic materials on the market, as well as different shapes and sizes of permanent magnets, so how to choose a suitable permanent magnet for your use? As long as you provide the following information (use, working temperature, working environment), our engineers will determine a suitable magnet for you.

Q: What can permanent magnets be used for?

This is a popular question when people talk about magnets. We can tell you that, "permanent magnets can be used in almost every commercial application, from industrial manufacturing to consumer electronics devices,and to new energy.

Q: What are neodymium magnets?

Neodymium magnets are made from an alloy of neodymium, iron and boron (Ndfeb). Though relatively small in size, they are famous for the amazing strength. Neodymium magnets are often referred to as "Ndfeb magnets" or "neo magnets. Neodymium permanent magnets are the strongest magnets in the world.

Q: How are neodymium magnets made?

Neodymium magnets of different shapes have different processing methods, the main processing methods are cutting, grinding, drilling,surface coating is important for neodymium magnets.

Q: Are neodymium magnets really that powerful?

Yes, they have the highest magnetic energy volume, and the neodymium magnet is known as magnet king( the strongest magnet on the market). In some cases, powerful neodymium magnets can cause serious damage.

Q: Which magnet is best for children?

Neodymium and Samarium cobalt magnets are rare earth magnets that can hurt children. Ferrite magnets are brittle and not suitable for children. Aluminium-nickel-cobalt magnets are weak enough for children to experience the characteristics of magnets

Q: Are magnets dangerous to pacemaker?

Close proximity to the magnet affects how the pacemaker works, as the magnet can cause the pacemaker not respond to the user's own heart rhythm. Different pacemakers react to magnetic fields in different ways, so people using pacemakers should not go near strong magnets.

Q: Will a magnet damage my mobile phone?

Small magnets won't do anything to your phone. However, strong magnets can make your phone lose its functionality quickly, so it is advisable to keep strong magnets away from any electronic devices, as strong magnetic fields may damage mechanical parts.

Q: Will a magnet damage my wristwatch?

If the tiny parts of the mechanical watch are made of metal materials, then when it is close to the magnet, it is likely to be magnetized. This causes the watch to run fast or slow or stop working altogether.

Q: What is the difference between permanent magnet and electromagnet?

A permanent magnet is a magnetized solid material that produces a stable magnetic field. Unlike permanent magnets, electromagnets create a magnetic field rely on an electric current,magnetic field disappears when the current is turned off.

Q: What types of permanent magnets are available?

There are five types of permanent magnets on the market, each with different characteristics. Neodymium-iron-boron and samarium-cobalt magnets are rare earth magnets with the strongest magnetic force. Ferrite magnets are made of ceramic materials with weak magnetism and low price. There are also aluminium-nickel-cobalt magnets and flexible rubber. 

Q: What are magnetic poles?

The region of a magnet where the magnetic field is strongest in a particular direction is the pole. There are N poles and S poles.If a magnet is divided into two parts, each part still has a north and South Pole.

Q: Which pole of a magnet is stronger

The magnetic strength at the north and south poles of a magnet is equal. The same poles of two magnets always repel each other, while opposite poles always attract each other.

Q: How to identify the poles of a magnet?

You can identify the poles with a professional pole identifier, and you can also  identify the poles with a compass.

Q: How to see the magnetic field?

You can sprinkle iron powder and iron filings on A4 paper, place the magnet under the paper and watch the iron filings move to reveal the magnetic field lines of any given magnet.

Q: What are rare earth magnets?

Permanent magnets made from rare earth elements in the periodic table are rare earth magnets, NdFeb and SmCo are the most widely used rare earth magnets. Rare earth magnets are stronger than other magnets.

Q: What is the !N rating! of neodymium magnet?

There are many different grades of neodymium magnets on the market, from N35 to N52, as well as other high temperature resistant neodymium magnets. The "N" grade is determined by multiplying the maximum energy of the magnet, which is a measure of the strength of the magnet. For example, an N35 neodymium magnet has a maximum magnetic energy of 35 MGOe and an N52 neodymium magnet has a maximum magnetic energy of 52 MGOe. In general, the higher the grade, the stronger the magnet.

Q: How to fix magnets in place?

Most magnets can be fixed in place with epoxy glue adhesive. We recommend Loctite Industrial Superglue. You can also use a 3M self-adhesive to hold a magnet on the non-metal place. We have self-adhesive magnets for sale.

Q: Can I cut or drill a magnet?

Most magnets (not including rubber magnets) are very hard and brittle, require professional equipment to process, and should be processed in an unmagnetized state, so do not attempt to cut or drill magnets
