The magnetic shielding device is mainly used to shield the environmental magnetic field, mainly the earth's magnetic field. The inside of the shielding tube can form a near-zero magnetic space (the magnetic induction intensity in the air is less than 1nT). To meet users' needs and requirements for a near-zero magnetic environment, the shielding tube has beautiful appearance, light weight, easy use and high cost performance.
