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 [...]

Does Magnet have radiation? Will it cause harm to body?

Does magnet have radiation to avoid? Will it cause harm to body? Recently, there has been such a message in the network: "The magnet has radiation, and you can see far away!" So, is the magnet that is very common in life and even used as a toy by many children, does it really cause [...]

How linear motors work

How linear motors work? In a traditional DC electric motor, a central core of tightly wrapped magnetic material (known as the rotor) spins at high speed between the fixed poles of a magnet (known as the stator) when an electric current is applied. In an AC induction motor, electromagnets positioned around the edge of the [...]

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, [...]


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 [...]

Magnetic Separators

Magnetic separators can utilize both permanent magnets and electromagnets which is used to separate ferrous materials from nonferrous materials. Magnetic Separators These items are ideal in manufacturing settings where metallic materials must be extracted to purify the process stream as well as for recycling applications. In many industrial applications, materials can be passed through, below, [...]

Industrial Magnets

Industrial magnets are high-strength magnets that have certain characteristics that make them ideal for applications in the industrial industry. In general, a wide spectrum of industries are increasingly using high-strength magnets to do all kinds of work, from physical metal lifting and separating to motor activation and Magnetic Resonance Imaging (MRI). Different applications require different [...]

Electric Hysteresis Brakes

Electromagnets are a non-permanent magnets that produced magnetic field. The magnetic field is created by a flow of an electric current through the coil. The magnetic field disappears when the current ceases (or in the caseelectromagnets of a permanent electromagnet, the magnetic field is present until a current is applied). Electromagnets As a [...]

Speaker drivers

A speaker drivers are an individual loudspeaker transducer that converts an electrical audio signal to sound waves. While the term is sometimes used interchangeably with the term loudspeaker (speaker), it is usually applied to specialized transducers which reproduce only a portion of the audible frequency range. For high fidelity reproduction of sound, multiple loudspeakers are often [...]

What is a homopolar motor? A homopolar motor is a direct current (DC) electric motor which produces constant circular motion. This device is easy to create and the figure below illustrates the basic concepts behind its operation. A permanent magnet is attached to one terminal of a DC power supply, in this case a AAA [...]

Electromagnetic Lock From Wikipedia

Electromagnetic Lock From Wikipedia An electromagnetic lock, magnetic lock, or maglock is a locking device that consists of an electromagnet and an armature plate. There are two main types of electric locking devices. Locking devices can be either "fail safe" or "fail secure". A fail-secure locking device remains locked when power is lost. Fail-safe locking [...]
