Surface Magnetism Field Surface magnetism refers to the magnetic induction intensity at a certain point on the surface of the magnet, and the unit is Gauss Gs or Tesla T (1T=10000Gs). The surface magnetism at different positions on the surface of the magnet is not the same. Generally speaking, "surface magnetism" refers to the center [...]
Magnetic Moment The generation of the magnetic field can be divided into two aspects: one is based on the moving current (electromagnetic induction), and the other is based on the spin of the basic particles of matter. The first is the magnetic effect of current that we are more familiar with, which is the magnetic [...]
Magnetic induction B and magnetic polarization J Practice and theory have proved that when a ferromagnetic or ferrimagnetic substance is magnetized in a magnetic field, in addition to the magnetic field in the substance, because the magnetic moments of the atoms of the ferromagnetic substance turn to the direction of the external magnetic field, it [...]
Permanent magnets in Apple's magnetic wireless charger Since the iPhone 8 in 2017, Apple has added a wireless charging function to all iPhone models, which is similar to other mobile phone wireless charging methods. It starts charging when placed on a wireless charger. This wireless charging relies on the transmitter coil and Accepting the alignment [...]
Magnetization direction and orientation direction The magnetism of permanent magnets mainly comes from its crystal structure that is easily magnetized. It can obtain extremely high magnetism under the action of a strong external magnetic field, and its magnetism will not disappear after the external magnetic field disappears. Therefore, "magnetization" is NdFeB A key step for [...]
How Helpful are Powerful Magnets in Daily Life? With the continuous advancement of technology, the use of powerful magnets is becoming more and more extensive, so where can powerful magnets be used in our daily life? What are the advantages of strong magnets that make many products widely used? HSMAG strong magnet How Helpful [...]

The Relationship Between Electricity and Magnetism Together, these two phenomena form the basis for electromagnetism Electricity and magnetism are separate yet interconnected phenomena associated with the electromagnetic force. Together, they form the basis for electromagnetism, a key physics discipline. Key Takeaways: Electricity and Magnetism Electricity and magnetism are two related phenomena produced by the electromagnetic [...]
Principle of Magnet Attraction and Repulsion Now that more and more people are using magnets, we want to start with some basic questions.How do magnets attract each other?How do they repel? The magnets written in middle school physics books have S poles and N poles. If the S poles or N poles of two magnets [...]
Working Principle of Magnetic Beads The main raw material of the magnetic beads is ferrite. The ferrite is a cubic ferromagnetic material with a cubic lattice structure. The ferrite material is iron-magnesium alloy or iron-nickel alloy. Its manufacturing process and mechanical properties are similar to those of ceramics. The color is grayish black. One type [...]
Wireless Energy Transfer Through Magnetic Fields If the inventor Nikola Tesla (1856-1943) was always with us, he would surely be very satisfied, since he thought of transmitting energy wirelessly almost a century ago. In fact, his idea was not so impossible to implement, since energy can now be transmitted over the wire using magnetic fields, [...]
Powerful magnets can kill cancer cells According to the British "Daily Express" reported on October 8, recently Korean scientists have made new breakthroughs in cancer therapy. They have developed a weapon against this disease, using powerful magnetic pulses to open the "self-destructive" inside the tumor. Switch to make cancer cells "suicide" effectively. The research was [...]
