Principle of Magnet Attraction and Repulsion

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 [...]

The Difference Between Magnetic Beads and Inductors

The Difference Between Magnetic Beads and Inductors The inductor is an energy storage component and the magnetic beads are energy conversion (consumption) devices. Inductors are mostly used in power supply filter loops, focusing on suppressing conducted interference; magnetic beads are mostly used in signal loops, mainly for EMI. Magnetic beads are used to absorb ultra-high [...]

Working Principle of Magnetic Beads

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 [...]

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 [...]

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 [...]

Electromagnetic Induction

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

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 [...]

Magnetic Attachment Wireless Charging

Magnetic Attachment Wireless Charging Apple Inc. launched their iPhone 12 series recently. Magnetic attachment wireless charging and MagSafe accessories attracted the most attention and analysis. Actually, Apple Inc. has been already utilized magnetic attachment wireless charging in their iWatch and Apple Pencil, then also obtained positive market feedback. As a new type of energy transmission [...]

How to Store Neodymium Magnets?

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

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

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

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 Keep the Entire World Running

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 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

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 [...]

Magnetism Electricity: Theory of Electromagnetism

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, [...]
