Magnet Common Sense

Magnet Common Sense As we all know, magnets are very useful in our daily life. To let those who are new to the world of magnets have a better understanding of them, in this article, we’ll introduce some common sense of magnets. A Brief History of Magnets The ancient Greeks and Chinese discovered a naturally [...]

  • Superconducting Magnet Construction

Superconducting Magnet Construction

Superconducting Magnet Construction A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire has no electrical resistance and therefore can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic [...]

The Basics of Magnetism

The Basics of Magnetism To understand what makes a material magnetic, you have to think small. Really small. Like atom small. Atoms are the basic building blocks that come together to form molecules, which come together for form, well, just about everything around you! Inside every atom there are protons, neutrons, and electrons. Protons have [...]

  • Select Material Grades for Neodymium Magnets

Select Material Grades for Neodymium Magnets

Select Material Grades for Neodymium Magnets When you are trying to figure out which neodymium magnets to select for your design needs, you would always see the term “grade” or “N rating” from any supplier or manufacturer. Besides a few other criteria, desired material grade must be defined for a neodymium magnet. So, what does [...]

  • B-H Curve for Permanent Magnets

B-H Curve for Permanent Magnets

B-H Curve for Permanent Magnets What is a B-H curve first of all? B is the nomenclature for magnetic flux density (induction) and H is magnetic field strength; a B-H curve plots out the relationship between them for a particular ferromagnetic material. The changes in magnetic flux density is dependent on the magnetic field strength. [...]

Permanent Magnets And Magnetic Behaviour

Permanent Magnets And Magnetic Behaviour Studying The Behavior Of Permanent Magnets Magnetic field is produced by objects known as magnets. When these properties of magnetism are not lost throughout time it’s known as a permanent magnet. So what is this special property in a permanent magnet that is not lost in the test of time? [...]

  • The difference between electromagnet and permanent magnet

The difference between electromagnet and permanent magnet

The difference between electromagnet and permanent magnet Electromagnets (solenoids) is a kind of electromagnetic equipment, which transforms electric energy into magnetic energy, and then transforms magnetic energy into kinetic energy (electric energy → magnetic energy → kinetic energy). First of all, the core is wound with a conductive winding matching its power. Such a coil [...]

World Strongest Magnets

World Strongest Magnets Buy extremely World Strongest Magnets - As a matter of fact, the neodymium magnets that we sell are currently the strongest permanent magnets on the market. Talking about "magnet strength", this means two things: 1. The attractive force or the magnetic field strength 2. The power of resistance to the destruction of [...]

  • Hard Magnetic Materials

Hard Magnetic Materials

Hard Magnetic Materials Magnetic materials can produce magnetic fields, which generate forces attracting or repelling ferromagnetic materials and other magnets. Magnetic material can be divided into soft and hard magnets. Soft magnets are those materials easy to magnetize and demagnetize, while hard magnets are difficult to do so and retain strong magnetism after the removal [...]

All About Magnetism and How it Works

All About Magnetism and How it Works From your clothes to your desk, every bit of matter is made of tiny particles called atoms. Atoms have negatively charged electrons that spin around them. Most of the time, the electrons spin in random directions. When the electrons all spin in the same direction, though, they create [...]

  • 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 [...]
