Magnetic Shielding MaterialIt is a material that can block magnetic field transmission and is widely used in fields such as electronic devices, communication systems, and medical equipment. Choosing suitable magnetic shielding materials can better meet the needs of target readers in low-frequency (DC to 100KHz) magnetic shielding. This article will introduce commonly used low-frequency magnetic shielding materials and conduct in-depth analysis from multiple dimensions.

1、 Soft magnetic materials

Soft magnetic materials are a common type of magnetic shielding material that can effectively absorb and disperse magnetic fields. Common soft magnetic materials include transformer core materials, inductor core materials, and soft magnetic paper in electronic devices. These materials have good magnetic permeability and saturation magnetic induction strength, which can effectively absorb and disperse external magnetic fields, thereby effectively shielding low-frequency magnetic fields.

For example, the core material of transformers is usually made of silicon steel sheets, which have high electrical resistivity and low remanence, and can effectively absorb and disperse low-frequency magnetic fields. In power transformers, using silicon steel sheets as the core material can reduce core losses and improve transformer efficiency.

2、 Ferrite material

Ferrite is a type of magnetic material with high saturation magnetic induction and low remanence. Ferrite materialsLow frequency magnetic shieldingIt has a good effect and can effectively absorb and disperse low-frequency magnetic fields. Common ferrite materials include soft ferrite and hard ferrite.

For example, soft magnetic ferrite has high saturation magnetic induction intensity and low remanence, which can effectively absorb and disperse low-frequency magnetic fields. Soft magnetic ferrite is commonly used in inductors, transformers, and electronic devices to improve their low-frequency magnetic shielding effect.

3、 Alloy materials

Alloy materials are materials composed of two or more metal elements, with high magnetic permeability and low electrical resistivity. Alloy materials exhibit excellent performance in low-frequency magnetic shielding, effectively absorbing and dispersing low-frequency magnetic fields. Common alloy materials include iron, nickel, cobalt, and copper. Alloy materials are widely used in low-frequency magnetic shielding in fields such as electronic devices, communication systems, and medical equipment.

For example, nickel iron alloy is a common magnetic shielding material with high magnetic permeability and permeability, which can effectively absorb and disperse low-frequency magnetic fields. Nickel iron alloy is commonly used in electronic devices and communication systems to enhance its low-frequency magnetic shielding effect.
