GUITAR PICKUP MAGNETS

GUITAR PICKUP MAGNETS - AlNiCo & Ferrite The magnetic pickup mounted on the Electric guitar's body help the sound production. A vibrating string cuts through the magnetic field in the pickup to produce a signal in the pickup's coil. What the magnets in pickup look like: Two type permanent magnets are used in pickups: AlNiCo [...]

Different Types of Sensors

Different Types of Sensors: Let us see the various types of sensors that are available in the market and discuss their functionality, working, applications etc. We will discuss various sensors like: Light Sensor IR Sensor (IR Transmitter / IR LED) Photodiode (IR Receiver) Light Dependent Resistor Different Types of Sensors Temperature Sensor Thermistor [...]

  • Magnetic Encoder Engine Technology

Magnetic Encoder Engine Technology

Magnetic Encoder Engine Technology An optical encoder uses light (optics) to identify unique positions for the encoder. A magnetic encoder uses the same principle to determine a position as an optical encoder, but it does it using magnetic fields rather than light. With a magnetic encoder, a large magnetized wheel spins over a plate of [...]

Magnet Materials

Permanent Magnet Materials Permanent magnet lodestones contain magnetite, a hard, crystalline iron ferrite mineral that derives its magnetism from the effect the earth's magnetic field has on it. Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico [...]

  • Magnet Background of permanent magnets

Magnet Background

Magnet Background A magnet is a material that can exert a noticeable force on other materials without actually contacting them. This force is known as a magnetic force and may either attract or repel. While all known materials exert some sort of magnetic force, it is so small in most materials that it is not [...]

  • History of Permanent Magnets

History of Permanent Magnets

History of Permanent Magnets Lodestones The history of permanent magnets goes back to ancient times. Records from early Greek, Roman and Chinese civilisations make reference to rare and mysterious stones called lodestones. These lodestones could attract each other and also small pieces of iron. When suspended from a thread it was noted that they always [...]

The Manufacturing Process of Sintered Neodymium Magnet

The Manufacturing Process of Sintered Neodymium Magnet - How Neodym Magnets are made? Sintered neodymium magnet is manufactured by vacuum powder metallurgy process. The manufacturing process is as follows: 1. Raw Material Neodymium (Nd), Iron (Fe), Boron (B) and other addictives are measured according to the preferred element composition. Raw NdFeB material Raw Material of [...]

How to Choose the Bushless Motor Magnets?

How to Choose the Bushless Motor Magnets? After you choose the slots and poles, you need to choose the magnets. This is not very easy task because you need high temperature magnets and are not so cheap and easy to find for your needed size. I bought custom made magnets from a Chinese SUPPLIER MPCO [...]

Grain Boundary Diffusion- Conserving HREE in NdFeB Magnets

Grain Boundary Diffusion- Conserving HREE in NdFeB Magnets Grain Boundary Diffusion is an important new advance in Neodymium magnet production technology. Heavy Rare Earth Elements (HREE) are delivered directly to critical areas of the magnet’s microstructure. These areas are where HREE are the most effective at increasing the properties of the magnet to withstand high [...]
