A Arrangement of Permanent Magnets – HALBACH ARRAY

A Arrangement of Permanent Magnets - HALBACH ARRAY A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. We can capture more magnetic field in using less magnets. Features A. Magnetic field on [...]

What Are Neodymium Magnet Speakers?

What Are Neodymium Magnet Speakers? Neodymium is an element with specific characteristics that make it particularly well suited for use in speaker construction. Speakers operate by using a magnetic field to generate motion in a coil and speaker cone to project an amplified sound signal. In neodymium speakers & loudspeakers, the rare-earth element is used [...]

Understanding Magnetic Permeability

Understanding Magnetic Permeability Magnetic Permeability is a value that expresses how a magnetic material responds to an applied magnetic field. If a material's internal dipoles become easily oriented to an applied magnetic field, that material is regarded as being a high-permeability material. If the material's internal dipoles do not become easily oriented to an applied [...]

Magnetism Magnetic Terminology and Definitions

Magnetism Magnetic Terminology and Definitions Formerly it was beleived that magnetism represented an independent physical phenomenon. It is a fact, however, that magnetic processes are connected to electric processes, that each electric process is a magnetic one at the same time, and vice versa. For a better understanding of physics related to magnets we have [...]

What is Speaker Magnet?

What is Speaker Magnet? The neodymium speaker magnet produces a magnetic field, and the speaker’s voice coil motor is placed in the magnetic field. When the voice coil passes through the audio current, the current will be acted by the magnetic field, which causes the voice coil to vibrate, and drives the paper basin that [...]

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 [...]

What Is Magnetic Field Therapy?

What Is Magnetic Field Therapy? Magnetic field therapy uses different kinds of magnets on the body to help boost your overall health. It may also help treat certain conditions. There are several types, including: Static magnetic field therapy: In this, you touch a magnet to your skin somehow. You might wear a magnetic bracelet or [...]

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 [...]

Axial Flux Motor Magnet

Axial Flux Motor Magnet, PM Axial Flux Motors Magnet, AXIAL FLUX ELECTRIC MOTOR MAGNETS, Axial and radial flux motors. As with other motor designs that include permanent magnets, PMAC axial flux motors exist. What is axial flux motor? An axial flux motor is different from conventional electric motors due to the different path of the [...]
