The materials of the electromagnet core are related to the size of the magnetism and should be determined according to the force you require. 12L14 class materials can make the iron core a little more powerful, but the material is softer. 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.

The vending machine motor drive electromagnet is made of electrician soft iron core, which is characterized by a small residual magnetism, and the current interruption magnetism disappears. If other materials are used, such as magnets, first, the magnetic field generated by the current may be opposite to the magnet magnetic field, and the comprehensive magnetic field is weaker; The magnetic force of electromagnets mainly relies on the magnetic field generated by the magnetic circuit, and your copper material is not magnetic.

Choose materials that can be attracted with magnetite. Because the resistance of the iron wire is large, under the same voltage, the current is much smaller, and the attraction of the electromagnet is determined by the current multiplied by the number of turns, and the current becomes smaller, and the attraction is insufficient. When there is no external magnetic field, the magnetism will disappear quickly, and there will be a magnetic field when electricity is applied, and the magnetism of other materials does not disappear as quickly as iron. Therefore, iron is chosen for this core.
