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 [...]
Electromagnetic Induction While Oersted’s surprising discovery of electromagnetism paved the way for more practical applications of electricity, it was Michael Faraday who gave us the key to the practical generation of electricity: electromagnetic induction. Faraday discovered that a voltage would be generated across a length of wire if that wire was exposed to a perpendicular [...]
Permanent Magnets Magnetism and Electromagnetism Centuries ago, it was discovered that certain types of mineral rock possessed unusual properties of attraction to the metal iron. One particular mineral, called lodestone, or magnetite, is found mentioned in very old historical records (about 2500 years ago in Europe, and much earlier in the Far East) as a [...]

How to Store Neodymium Magnets? Neodymium magnets have special properties and require specific storage environment to avoid losing their magnetic strength, being irreversibly damaged or cause hazards to their surroundings. When selecting a storage for your magnet material, take the followings into consideration: Humidity: Neodymium magnets are prone to corrosion in moist environment due to [...]
Two Advantages of Electromagnet Over Permanent Magnet Magnets come in two main types: permanent magnets and electromagnets. As its name suggests, a permanent magnet is always magnetized -- think of a kitchen magnet that stays stuck to a refrigerator door for years. An electromagnet is different; its magnetism works only when powered by electricity. Although [...]
Electro Circular Magnets EHRP-ND electro-permanent magnets consist of a circular permanent-magnetic adhesive system and from an excitation winding permitting neutralized in the ON state, the magnetic field to the adhesive surfaces and thus the removal or withdrawal of the workpiece. Because of the permanent-magnetic character of EHRP-ND round magnets these are preferably used where long [...]
Permanent Magnetic Clamping Blocks A style permanent magnetic clamping blocks have 3 clamping sides (top, left and right side surface) and can be switched via the front panel. On the top there is a cross prism. Main areas of application can be found in the grinding and measuring. Angularity 0.025mm, 0.015mm parallelism. B style permanent [...]
Some Permanent Magnets that Keep the Entire World Running Rare earth or perpetual are made from components in the rare earth assembly of the occasional table of the components. While once acknowledged rare, these components have been discovered to be as normal as lead or tin. Be that as it may, their helpfulness in changeless [...]
LAMINATED MAGNET ASSEMBLY LAMINATED MAGNET ASSEMBLY is to cut the whole magnet into many small pieces of magnet, and then use specific glue to bond together. These small magnets are insulated from each other and enable to cut down electromagnetic eddy current. When the permanent magnet motor is running, the motor will generate harmonic and [...]
Hall Effect Encoder Overview A hall effect encoder uses a hall-array sensor passed over a magnetic field to produce a signal that is then interpolated to resolution. HSMAG hall effect magnetic encoders use a magnetic phased array sensor to average the signal over multiple detectors to deliver a robust, high resolution signal that is insensitive [...]
Design and Recycling of Rare-Earth Permanent Magnet Motors and Generators in Hybrid and Full Electric Vehicles DEMETER – European Training Network for the Design and Recycling of Rare-Earth Permanent Magnet Motors and Generators in Hybrid and Full Electric Vehicles In 2010 the European Commission (EC) published a milestone report on Critical Raw Materials (CRM) for [...]
Cochlear Implant (CI) Magnet The purpose of the cochlear (COKE le ar) implant (CI) magnet is to hold the headpiece (coil) in place to transmit sound to the internal device. The entire device has 4 parts: the magnet, headpiece (coil), cable and processor. The CI magnet portion is about the size of a dime. Before [...]

Hi-Intensity Electromagnetic Separators – Exclusively vacuum impregnated coils for higher operating strength and greater heat dissipation performance. 3-Styles: Suspended / Automated Self-Cleaning Cross Belt / Auto In-Line Belt Ø CLASS “H” Fiberglass insulated [...]
Magnet Attracting Repulsion Principle Magnet Attracting Repulsion - Now more and more people are using magnets, we want to discuss some of the most basic issues with you first. How do magnets attract each other? How are they excluded? How to make the screwdriver magnetized? Magnet basics magnets can attract each other or repel each [...]
What use are magnets? Maybe you think magnets are interesting; maybe you think they're boring! What use are they, you might ask, apart from in childish magic tricks and scrapyards? You might be surprised just how many things around you work by magnetism or electromagnetism. Every electric appliance with an electric motor in it (everything [...]
Magnetism Electricity: Theory of Electromagnetism Electromagnets show that you can make magnetism using electricity. In fact, as European scientists discovered in the 19th century, electricity always makes magnetism when it moves about or changes. Every time an electric current flows in a wire, it generates a magnetic field all around it. Changing electricity, in short, [...]
Synchronous Generators Definition: The synchronous generator or alternator is an electrical machine which converts the mechanical power from a prime mover into an AC electrical power at a particular voltage and frequency. The synchronous motor always runs at the constant speed called synchronous speed. Synchronous Generators Working Principle of Synchronous Generator The synchronous [...]
Rare Earth Permanent Magnet Application Classification based on Operation Principle Rare earth permanent magnet can be classified into five types according to its operational principle, includes Lorentz Force Effect, Ampere’s Circuital Law, Faraday’s Law of Electromagnetic Induction, Coulomb’s Law for Magnetism and other magnetic effects. Actually, each operational principle has extremely widespread application area. Lorentz Force [...]
Decrypt NdFeB Magnets - The formation of a magnetic field is a magnetic field generated by a molecular ring current of a magnetic substance, and the direction of movement of atoms or ions outside the nuclear electrons is random, so a large number of atom synthesis current is zero, no magnetic field, such as ferric [...]
An electromagnet is a type of magnet that is composed of a battery and iron wire that uses electric current in order to generate a magnetic field. Electromagnet The magnetic field is generated when the electric current passes through a wire, and the field dissipates when the current stops. The primary function of electromagnets is [...]
Electric Hysteresis Brakes These brakes utilize an electromagnet to generate drag torque Drag torque is dependent on input current and independent of slip speed, a constant current power supply such as our MPP24 must be used Torque on each unit can be adjusted to any value between bearing drag (~0) and the max torque indicated [...]
