Magnet - Wikipedia

Magnets can be used in scrap and salvage operations to separate magnetic metals (iron, cobalt, and nickel) from non-magnetic metals (aluminum, non-ferrous alloys, etc.). The same idea can be used in the so-called "magnet test", in which an auto body is inspected with a magnet to detect areas repaired using fiberglass or plastic putty.

Magnetic Shielding Materials - lessemf.com

Decorative Magnetic Shielding. A circuit breaker box (or fuse box) in the bedroom, living room, kitchen, or other living space can be a real problem. Strong magnetic field emissions (depending on how much electric current is flowing) and electric field emissions can make the nearby area hazardous to occupy, especially for long periods.

Frequently Asked Questions: EMF Shielding

The magnetic field from a powerline decreases with distance, for sure. But the magnetic field from a powerline varies from moment to moment depending on how much current is flowing in the wire at the time. It will be higher during peak electricity usage times.

Tips on shielding and grounding in Industrial Automation ...

Figure 29 – The length of the ground-reference connection should be minimized as it works as a coil. Electric fields are much easier to shield than magnetic fields and the use of shielding on one or more points work against electric fields. The use of non-magnetic metals around conductors does not shield against magnetic fields.

Magnetometer - Wikipedia

A magnetometer is a device that measures magnetism—the direction, strength, or relative change of a magnetic field at a particular location. The measurement of the magnetization of a magnetic material (like a ferromagnet) is an example.A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field.
