Web11 apr. 2024 · A pair of Earth, atmospheric and planetary scientists at Massachusetts Institute of Technology has shown how the magnetic field of a meteorite can be damaged by amateur collectors using hand magnets. WebSeveral companies manufacture earth testers, also known as earth ground testers. The main use of these instruments is to test the resistance of grounding rods. Grounding rods placed in the soil protect a home's wiring system by directing electrical surges into the ground. Over time, grounding rods corrode and become less effective.
