Magnetic coils and yokes, demagnetizing coils and yokes, and other search coils, etc.

A unique item tailored to your needs!

The magnetic yoke and air-core coil are designed to set permanent magnets or permanent magnet products, converting the large pulse currents flowing from the capacitor-type pulse power supply and the magnetizing power supply into a magnetic field. This magnetic field imparts magnetism to the permanent magnets. If this design is defective, even if a high-performance magnetizing power supply is purchased, it may reduce the performance of the magnetic yoke by half. Our company utilizes its abundant technology and experience to design the most rational magnetic yokes and coils. Additionally, we provide designs tailored for search coils, search yokes, Helmholtz coils, and solenoid coils.
