Thank you very muchscottdave said:
Magnetic shielding is a process in which a material is used to create a barrier that reduces or eliminates the effects of a magnetic field on a specific area or object.
Magnetic shielding is important because it can protect sensitive electronic equipment, such as computers and medical devices, from interference caused by magnetic fields. It can also prevent magnetic fields from affecting nearby objects or environments.
The most commonly used metals for magnetic shielding are iron, nickel, and cobalt. These metals have high magnetic permeability, which means they can easily redirect magnetic fields.
Magnetic shielding works by creating a barrier of highly permeable material around the object or area that needs protection. This material redirects the magnetic field lines, reducing their strength and preventing them from affecting the protected area.
There are several techniques for measuring the effectiveness of magnetic shielding, including magnetic field mapping, gaussmeter measurements, and magnetic flux density measurements. These techniques can determine the strength of the magnetic field before and after shielding, providing a measure of the shielding's effectiveness.
