Do Magnet Coating Affect Magnet Strength?

Do Magnet Coating Affect Magnet Strength? Some customers ask whether the magnet coating will affect its magnetic strength from time to time? How big is the impact? Let's talk about this topic today. This is indeed an important factor to be considered. Although the distance of one or two millimeters between the magnet and another [...]

What is Ferromagnetic Paper?

What is Ferromagnetic Paper? Ferromagnetic paper is formed by impregnating ordinary paper or newspaper with "magnetic nanoparticles". It can be used to make low-cost "micro-motors" for surgical instruments, tiny tweezers to study cells, tiny robots and tiny speakers. At present, the researching people will also ferromagnetic origami paper, to study more complicated design. Ferromagnetic paper [...]

Understand the Electromagnetic Spectrum

Understand the Electromagnetic Spectrum Begin with naming all the parts. There are 8 parts to the Electromagnetic Spectrum. They are: Radio Waves Microwaves Terahertz Radiation Infrared Light (IR) Visible Light Ultraviolet Rays (UV) X-Rays Gamma Rays By understanding these names, you will need to know its range. Below is showing a table of the range. [...]

Magnetic Particle Examination

Magnetic Particle Examination Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic is defined in ASME Section V as “a term applied to materials that can be magnetized or strongly attracted by a magnetic field.” MT is an NDE method that checks for surface discontinuities [...]

How to Determine Polarity of Magnets

How to Determine Polarity of Magnets You might have heard the phrase “opposites attract.” While perhaps not always the best advice for relationships, this cliché is the rule of thumb for magnet polarity. Since we inhabit a giant magnet (Earth), understanding magnet polarity on a small scale will help you understand the larger magnetic field [...]

What You Need to Know About This Polarizing Healthcare Designation It takes a large team of clinical and administrative professionals to successfully operate a healthcare facility. But when it comes to directly working with patients, nurses are on the front line. Whether in clinics, hospitals or other facilities, nursing professionals [...]

Electromagnetic Radiation Definition

Electromagnetic Radiation Definition Electromagnetic radiation is self-sustaining energy with electric and magnetic field components. Electromagnetic radiation is commonly referred to as "light", EM, EMR, or electromagnetic waves. The waves propagate through a vacuum at the speed of light. The oscillations of the electric and magnetic field components are perpendicular to each other and to the [...]

Hands-on Electromagnetic Experiments and Electromagnet FAQ

Can't get enough of hands-on electromagnetic experiments? We have some more ideas for you to try: What is the magnetic power of a single coil wrapped around a nail? Of 10 turns of wire? Of 100 turns? Experiment with different numbers of turns and see what happens. One way to measure and compare a magnet's [...]

Electromagnets All Around Us

Electromagnets All Around Us Many electromagnets have an advantage over permanent magnets because they can be easily turned on and off, and increasing or decreasing the amount of electricity flowing around the core can control their strength. Modern technology relies heavily on electromagnets to store information using magnetic recording devices. When you save data to [...]

How to Make a Super Power Electromagnet

How to Make a Super Power Electromagnet Building a super-power electromagnet is really no different than building a simple nail-and-copper-wire kind. The difference is that you want a better core, more power and more dense windings. To that end, this project uses a ferrite rod instead of an iron nail, a power supply instead of [...]

How to Confirm a Good Magnet Supplier?

How to Confirm a Good Magnet Supplier manufacturer? Emailing or calling them is a key factor. A China's magnet factory or trader may not be able to fully display their content on the website. We need to communicate our needs to determine whether this is what I am looking for China's magnet factory. And in [...]


PROCESS FOR RECOVERING RARE EARTHS AND METALS Exhausted magnets recovery Hydrometallurgical process Liquid-solid discharge Neodymium INTRODUCTION The present invention concerns a hydrometallurgical process whose main purpose is the recovery of the materials that make up the exhausted permanent magnets; in particular the elements belonging to the group of rare earths such as Neodymium and Praseodymium [...]

Wireless Energy Transfer Through Magnetic Fields

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, [...]

1800 After History of Magnetism and Electricity

1800 After History of Magnetism and Electricity 1820 - Electromagnetism, Current In 1820, a physicist Hans Christian Oersted, learned that a current flowing through a wire would move a compass needle placed beside it. This showed that an electric current produced a magnetic field. Andre Marie Ampere, a French mathematician who devoted himself to the [...]

Before 1800 History of Magnetism and Electricity

Before 1800 History of Magnetism and Electricity 600 BC - Lodestone The magnetic properties of natural ferric ferrite (Fe3O4) stones (lodestones) were described by Greek philosophers. 600 BC - Electric Charge Amber is a yellowish, translucent mineral. As early as 600 BC the Greek philosopher, Aristophanes was aware of its peculiar property: when rubbed with [...]

Magnetism FAQ

Magnetism FAQ Basic Electricity Question 1 A permanent magnet is a device that retains a magnetic field without need for a power source. Though many of us have experienced the effects of magnetism from a permanent magnet, very few people can describe what causes permanent magnetism. Explain the cause of permanent magnetism, in your own [...]

Magnetic Units of Measurement

Magnetic Units of Measurement If the burden of two systems of measurement for common quantities (English vs. metric) throws your mind into confusion, this is not the place for you! Due to an early lack of standardization in the science of magnetism, we have been plagued with no less than three complete systems of measurement [...]

How do Magnetic Filters Work?

How do Magnetic Filters Work? While a large number of configurations exist, most magnetic filters work by producing a magnetic field or loading zones that collect magnetic iron and steel particles. Magnets are geometrically arranged to form a magnetic field having a nonuniform flux density (flux density is also referred to as magnetic strength) Particles [...]
