Magnetic field Electromagnet is a device that can generate magnetic force by passing an electric current. It is a non-permanent magnet and can be easily activated or deactivated. Example: Large cranes use electromagnets to lift abandoned vehicles.

Magnetic field Electromagnet manufacturers tell you that when current is passed through a wire, a magnetic field is generated around the wire. Using this property, when an electric current is passed through a solenoid, a uniform magnetic field is created within the solenoid. Assuming that a ferromagnetic substance is placed in the center of the solenoid, the ferromagnetic substance will be magnetized and the magnetic field will be greatly enhanced.
Generally speaking, the magnetic field generated by the magnetic field electromagnet is related to the magnitude of the current, the number of coil turns and the ferromagnet in the center. When designing electromagnets, attention is paid to the distribution of coils and the selection of ferromagnets, and the magnitude of the current is used to control the magnetic field. Magnetic field Electromagnet manufacturers tell you that due to the resistance of the material of the coil, this limits the size of the magnetic field that the electromagnet can generate, but with the discovery and application of superconductors, there will be opportunities to surpass the existing limitations.
