Magnets are very important materials in our world today. Actually, a vast amount of the technology that exists today is practically inconceivable without magnets. But researchers have moved beyond the relevance of magnets on earth, and are already exploring the use of magnets in space. Interestingly, it turns out that there is a lot that

Permanent Magnets Used in Electronics and Computers
Introduction In history, magnets were first mentioned in 600 BCE when Lodestone was discovered. Since then, magnets have had several uses. The most interesting of these uses is the use of magnets in computers and electronics. Magnets and Electricity As far back as the 19th century, a link was found between magnets and electricity. A

Why and How Magnets Can Generate Electricity?
Introduction In the early 1820s, Michael Faraday, an English scientist, was able to generate electricity by moving a loop of wire between the poles of a magnet. And he posited the first principle for generating electricity. Electrical energy obeys the first law of thermodynamics which states that energy can neither be created nor destroyed but can

Magnetic Compasses and Navigation Systems
History Before magnetic compasses became popular, mariners used the position of the stars for navigation. They used the position of a northern star called Polaris as the reference point. This method of navigation came with its challenge. It was quite difficult for sailors to study the stars on cloudy or foggy days. In the 12th

An Introduction to Vibrating Sample Magnetometer
A vibrating sample magnetometer is an instrument that is used to measure magnetic properties. It is also called a Foner magnetometer. This instrument works based on Faraday’s Law of Induction which states that induced voltage in a circuit is directly proportional to the changing magnetic field in the circuit. In 1955, Simon Foner, a scientist

Permanent Magnetic Synchronous Motors
What Are Permanent Magnet Synchronous Motors? The permanent magnet synchronous motors (PMSM) are similar to the traditional AC synchronous motors, but the field, in this case, is excited by permanent magnets that create sinusoidal back EMF. They are similar to typical rotating electric motors that consist of a rotor and a stator. However, permanent magnet

Permanent Magnets Used in the Foundry Industry
Industrial Application of Magnets Permanent Magnets are common items in our world today. But to a lot of people, what mostly comes to mind at the mention of magnets may be stickers on refrigerator doors or something that sticks together with metallic components. But there is a whole world of special magnets classified as industrial

Permanent Magnets Used in Plastic Industry
The use of permanent magnets in different manufacturing processes is a common practice in today’s manufacturing industry. The most important use of magnets is in the removal of metal contaminants from plastic products. Meanwhile, magnets play important roles in other industries, such as the electronics, mining, and foundry industries. The plastic industry also uses magnets

Permanent Magnets Used in Electric Guitar
Magnets are a fundamental unit in every electric guitar, without which the guitars may not function. Electric guitar pickups typically contain one or two magnets to generate a magnetic field from the electrical impulse. The two most commonly used permanent magnets used in guitar pickups are AlNiCo magnets and ceramic magnets. What are Guitar Pickups?

General Information About AlNiCo Magnets
AINiCo magnets are a special type of magnet mainly composed of aluminum, nickel, and cobalt. These magnets can also include titanium, iron, and copper. They come in two forms; the isotropic, non-directional form, or the anisotropic, mono-directional form. Once they’re magnetized, they typically have 5 to 17 times the magnetic force of magnetite or lodestone. These
