A device that is made up of something is called an electromagnet

The electromagnet is mainly composed of: skeleton, wire package, shell, cover plate, slide bar, ejector rod, iron core, etc.

For details, please enter Shenzhen Zhongheng Electric**. Make a more comprehensive image of the understanding.

What is an electromagnet called?

The electromagnet is made according to the principle that the energized coil generates an acoustic magnetic field, in fact, Oster found that the energized conductor can produce a magnetic field, and due to the weak magnetic field generated, it was later discovered that the energized coil can generate a magnetic field. In order to increase his magnetic **, an iron core was added to the middle of the circle. The device thus made is called an electromagnet.

It is mainly used for electrical control and the discovery of ferromagnetic materials, such as old-fashioned mine detectors.

An energized solenoid with an iron core inside is called an electromagnet. When an iron core is inserted inside an energized solenoid, the iron core is magnetized by the magnetic field of the energized solenoid. The magnetized core also becomes a magnet, so that the magnetism of the solenoid is greatly enhanced due to the superposition of the two magnetic fields on top of each other.

In order to make the electromagnet more magnetic, the iron core is usually made hoof-shaped. However, note that the upper coil of the hoof core is wound in opposite directions, clockwise on one side and counterclockwise on the other side. If the winding direction is the same, the magnetization of the core by the two coils will cancel each other out, making the core non-magnetic.

In addition, the core of the electromagnet is made of soft iron, not steel. Otherwise, once the steel is magnetized, it will remain magnetic for a long time and cannot be demagnetized, and its magnetic strength cannot be controlled by the size of the current, and the due advantages of the electromagnet will be lost.

Electromagnets.

An electromagnet is a device that converts electrical energy into magnetic energy.

An electromagnet is a device that generates electromagnetism when energized. A conductive winding that matches its power is wound around the outside of the core, and the coil that is emung with current is magnetic like a magnet, and it is also called an electromagnet. We usually make it into a bar or hoof shape to make the core more easily magnetized.

In addition, in order to degauss the electromagnet immediately when the electromagnet is deenergized, we often use soft iron or silicon steel materials that demagnetize quickly. Such an electromagnet is magnetic when energized, and the magnetism disappears when the power is off. Electromagnets have an extremely wide range of applications in our daily life, and the power of generators has been greatly improved due to its invention.

Devices of this structure are approximately:

Reactors, transformers, transformers. AC contactors, electromagnets. chokes and other ......

Electromagnets, if there are multiple turns of coils, may also be transformers.

Transformer solenoid valve

A device consisting of an iron core and a solenoid coil is called an electromagnet. Electromagnets are made based on the principle that energized wires can generate (magnetic fields).

The first one (magnetic, produces magnetism) and the second one (magnetic).

The principle used is Faraday's electromagnetic induction.
