  • Magnetic force on a wire

What is magnetic force?

What is the magnetic force? The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them. Similarly, objects with charge moving in opposite [...]

N35 And N52 Magnet

N35 And N52 Magnet In the marketing process, some customers do not understand the meaning of the N35, N52 magnet, then what is the matter? In the market, we talk about the neodymium iron boron magnetism. Actually, there are many material grades in the strong magnetism. The magnetic energy product in each grade is different. [...]

Chemically Controlled Magnetic Material

Chemically Controlled Magnetic Material Magnets are common in physics classes at school, but almost no chemistry classes are involved; researchers have successfully used chemical methods to control the magnetic properties of ferromagnetic substrates. Physical methods may affect the direction of the magnetic field. The chemical method in this example finely controls the selected ferromagnetic material [...]

Three Factors Affecting Magnetic Force

Three Factors Affecting Magnetic Force of Magnet In the recent work, many customers are asking if the magnet will demagnetize? What is the longest life of a magnet? When will the magnet demagnetize? Waiting for a series of such questions, I will probably share with you the information I have learned in the magnet industry. [...]

  • Hydrogen Embrittlement Failure of NdFeB Magnet

Hydrogen Embrittlement Failure of NdFeB Magnet

Hydrogen Embrittlement Failure of NdFeB Magnet Hydrogen embrittlement is a process by which hydride-forming metals become brittle, even fracture due to the penetration of hydrogen gas, and mechanical strength of relevant material will dramatically decrease because of hydrogen embrittlement. People have been studying how to prevent hydrogen embrittlement for over the past several decades. [...]

  • MAGNETIC POLES

MAGNETIC POLES

MAGNETIC POLES The magnetic force surrounding a magnet is not uniform. There exists a great concentration of force at each end of the magnet and a very weak force at the center. Proof of this fact can be obtained by dipping a magnet into iron filings (fig. 1-8). It is found that many filings will [...]

Why compass can be inaccurate

Why compass can be inaccurate Compasses are brilliantly useful but they can sometimes lead us astray, because of two quite different problems called declination (or variation) and deviation. Here's why. compass Declination (variation) Earth spins about an axis (a kind of invisible rod) running through the north pole (sometimes called the geographic north [...]

  • How do compasses work

How do compasses work?

How do compasses work? Artwork: Earth behaves as though it has a giant bar magnet built inside it. But the magnet is the opposite way around to how you might think, with its south pole up near Earth's actual (geographic) north pole and vice-versa. A compass needle points north because the north pole of the [...]

What is a Magnet Hospital?

What Is Magnet Hospital A Magnet hospital is a healthcare facility that is identified as having exceptional nursing standards as well as a good work environment for nurses. Hospitals and other facilities apply for this status through the The American Nurses Credentialing Center's (ANCC) Magnet Recognition Program® (MRP). If they meet criteria in five areas [...]
