The direct suction of a powerful magnet may cause a pinch wound, especially the neodymium magnets and large magnets. 1. Magnets may more serious injury from the mouth into the body, may hurt life, because the magnet itself with magnetism, mutual absorption in the body will cause intestinal perforation, and then cause massive bleeding, the

How is Halbach Array Used in Electric Motors
Halbach array electric machines could be constructed in a conventional manner, whereby the Halbach array is stationary and the windings rotate within the array. In a conventional machine configuration, the Halbach array machine would look physically much like a DC machine; that is, the armature is on the rotor and the field is stationary. Such

What Are The Four Types of Magnets?
There are many kinds of magnets, which are generally divided into two categories: permanent magnet and a soft magnet. Permanent magnet is divided into two categories. The first category is metal alloy magnets, including neodymium iron boron magnets, samarium cobalt magnets, and aluminum nickel cobalt magnets. The second major categories are ferrite permanent magnets. 1.

Magnetic Field Distribution of Neodymium Ring Magnets
The magnetic field distribution of the neodymium ring magnet is as follows: the inner space of the ring still belongs to the outer magnetic field distribution, and part of the magnetic induction line connects the magnetic poles of both ends through the inner hole of the ring. What is the magnet? A magnet is a

List of Magnets That Can Withstand High Temperatures
The normal working temperature of the magnet is 80℃. If it passes through high temperature, that is, over the normal working temperature of 80 ℃, demagnetization will occur. Theoretically speaking, the maximum temperature resistance of the magnet is about 230 ℃, and the actual working temperature is also dependent on the actual working temperature. 1.

High Temperature Resistance Magnets
Three environmental factors affecting the function of high-temperature magnet Ambient temperature Because the sintered NdFeB has a negative temperature coefficient （αBr<-0.13%/℃，αHcj<-0.6%/℃）, the highest instantaneous temperature and the continuation of the highest temperature will demagnetize the magnet to varying degrees, including reversible and non-reversible, recoverable and non-recoverable. Ambient humidity Neodymium is easy to corrode and oxidize.

From Flat Panel TV to Smart Phone — Nothing Boring About Boron
Every time you watch sports on a flat-panel TV or send a message by touching a smartphone screen, please thank an unsung hero in the periodic table: Boron. Boron is often wrongly labeled the “boring” element, but it is versatile and plays an important role in our lives. It is a key component of borosilicate

Why Neodymium Magnets are so Strong?
Neodymium permanent magnet is widely used in the fields of electronics, electric machinery, medical equipment, toys, packaging, hardware machinery, aerospace and aviation. The most common are permanent magnet rotor, loudspeaker, magnetic separator, computer disk drive, magnetic resonance imaging equipment and instruments. Neodymium magnets can be processed by Nano (Royce3010) chelate thin film coating, which can
