  • Testing Magnetic Field Range with Paperclips

Testing Magnetic Field Range with Paperclips

Testing Magnetic Field Range with Paperclips Make a holder for a bar magnet. You can make a simple magnet holder using a clothespin and a paper or Styrofoam cup. This method would be suitable for teaching elementary school-age students about magnetic fields. Tape one of the long ends of a clothespin to the bottom of [...]

  • The Role of Strong Magnets in Salt Spray Test

The Role of Strong Magnets in Salt Spray Test

The Role of Strong Magnets in Salt Spray Test Salt spray test of strong magnet: refers to an environmental test that uses artificial simulated salt spray environmental conditions created by salt spray test equipment to assess the corrosion resistance of product surfaces. Generally, 5% sodium chloride salt solution is used, and the pH value of [...]

  • Common Coatings of Sintered NdFeB Magnet

What are the Common Coatings of Sintered NdFeB Magnet?

What are the Common Coatings of Sintered NdFeB Magnet? Sintered ndfeb magnetic coatings are nickel, copper, chromium, gold, zinc, black zinc, epoxy resin. Its surface electroplating is not the same, its color is not the same, its preservation time is not the same, each has advantages, but also has disadvantages. 1) zinc: the surface looks [...]

  • Magnetization and Magnetic Intensity

Magnetization and Magnetic Intensity

Magnetization and Magnetic Intensity We have all played with magnets as children. Some of us even play with them now! But, what makes them ‘magnetic’? Why don’t all the materials and substances possess a magnetic field? Have you ever wondered about it? In this chapter, we will cover the topics of magnetization and magnetic intensity. [...]

  • How Does Temperature Affect Magnetism of Magnets

How Does Temperature Affect Magnetism of Magnets?

How Does Temperature Affect Magnetism of Magnets? - Magnets are used in daily life. They’re used in manufacturing, automobiles, security systems and electronics devices. Even the earth itself is a magnet. How does temperature affect the magnetism of magnets? To understand temperature effects, we need to look at the atomic structure of the elements that [...]

How to Control the Quality of Neodymium Magnets?

How to Control the Quality of Neodymium Magnets? Permanent Neodymium magnet, chemically known as NdFeB, is known as the most significant magnet material with high performance and are widely applied in many industrial fields. To manufacture the highest quality magnet products, we need to assure the accuracy of: magnetic property, physical dimensions and surface plating. [...]
