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 [...]
Magnetic Performance Testing I. Magnetic Performance Test 1. Magnetic property detection A) test iteMs: Br, Hcb, Hcj, (BH)max, Hk, ms, μrec, Hk/ Hcj, etc. B) testing instrument: hysteresis loop tester C) test range: Hcj 50~20,000 Oe 2. High and Low Temperature Magnetic Properties Any temperature between -40 and 250 ºC can be tested. 3. Reversible [...]
Look Neodymium Magnet's Rust While this blog promotes the use of neodymium magnets, we also try to be frank about their limitations. Previous examples include: How a neodymium magnet doesn’t remove all the data from a hard drive, Pacemaker Safety, How fragile magnets are – Breaking Magnets, and How Magnetic Paint isn’t very attractive. In [...]
What is a High (Super) Strength Magnet? I often hear customers call our merchandiser to buy high-strength magnets and ask if we can do it here. So what is a high-strength magnet? Where are high-strength magnets commonly used? Today this article will introduce to you. What is a high(super)strength magnet? high-strength magnet According to the [...]
Difference between nickel plating and zinc plating neodymium magnet The most commonly used coatings for NdFeB magnets are galvanized and nickel-plated. They have obvious differences in appearance, corrosion resistance, service life, and price. Many people ask about the difference between galvanizing and nickel plating on magnets. What are the differences in appearance, price and rust [...]
What's the difference between galvanized and nickel-plated magnets? The most commonly used coatings for NdFeB magnets are galvanized and nickel-plated. They have obvious differences in appearance, corrosion resistance, service life, and price. Polishing difference: nickel plating is superior to zinc plating in polishing, and the appearance is brighter. Those with high requirements for product appearance [...]
FOR WHAT PURPOSES CAN YOU USE CUSTOM MAGNETS Custom magnets (what we talk about is refrigerator magnets) are used for various purposes. But in this article, we are going to discuss their special shape of. For people who are planning to expand their company or business, these custom magnets are the easiest way to promote [...]
Magnetisation and Laws of Magnetism The magnetisation of a material is done by electric current and there are various laws of magnetism to explain. The magnetisation of a material is done by electric current. A material is first magnetised after the magnetic materials are transformed into the required shapes, sizes and designs. Then they can [...]
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. [...]
Magnetized Oils - Ferrofluid Oil can be magnetized in an approximately similar fashion as of magnetization of water with the exception that the oils need a longer duration of exposure to magnets in order to assimilate the beneficial properties of the latter. Oils are prepared either on the North Pole or the South Pole and [...]
Properties of Magnets Properties of Magnets are many. Most prominent property of magnet is that it has two poles and it attracts objects like iron, cobalt and nickel. There are several prominent and noteworthy properties of magnet. It is a known fact that magnet has two poles, namely, north and south, but these two poles [...]
Magnets in Vedas The ancient Atharva Veda has the reference of some magnet like materials in the treatment of various diseases. Magnet is said to have very ancient origin and its properties were known to the very ancient Aryans. They have the belief that the magnet, besides having the power of attracting iron, was also [...]
