What is a frame electromagnet

Frame type electromagnet, also known as box type electromagnet, because its shape is square. This frame electromagnet is a device that generates electromagnetic waves. When the transformer core rotates externally and its output power is consistent with the resistance of the conductive winding, the coil with current has the same magnetism as the magnet. We usually make it into a strip or hoof shape to make its transformer core more easily magnetized. In addition, in order to immediately power off and demagnetize the electromagnet, we often use fast demagnetized soft iron or silicon steel materials for production. This type of electromagnet becomes magnetic when plugged into a power source. When the power is turned off, the magnetic field will disappear. Square electromagnets have many uses in our daily lives, as their generation also greatly improves the output power of the generator set.
Principles of Electromagnetic Communication
Let's first take a look at the composition principle of an electromagnet: an electromagnet is mainly composed of a coil, an iron core, and an armature. The iron core and armature are generally made of soft magnetic materials. It is generally divided into DC electromagnets and communication electromagnets. What is the principle of a communication electromagnet?
When the communication electromagnet coil is inserted, the iron core and armature are magnetized, becoming two magnets with opposite polarity. When the adsorption force exceeds the reaction force of the tension spring, the armature turning point moves towards the direction of the iron core. When the current in the coil falls below a certain value or the power supply is interrupted, the electromagnetic absorption force is lower than the reaction force of the tension spring, and the armature will return to the original release direction under the action of the reaction force.
It is worth noting that the electromagnetic absorption force of communication electromagnets is composed of the magnetic field of the magnetic separator and the magnetic field of the magnetic separator. The magnetic field force of two alternating electric fields, combined with the net weight of DC, is more easily released, resulting in low output power, large transformer core volume, and high coil energy consumption; Low power factor, high coil current, and severe heating not only waste electrical energy, but also cause premature aging and damage to the coil.
