Earth's electromagnetic fields work
WebMost of these magnetometers work by exploiting the force an electron feels as it moves through a magnetic field. Very accurate measurement of small magnetic fields has only been practical since the discovery in 1988 of giant magnetoresistance in … WebHz electric and magnetic fields. Even some of the work environments which would be clearly considered to be "electrical work," such as electrical utility lineman, were below these guidelines. The average electrical field measured in a typical office environment was below 0.01 kV/m and the magnetic field was only about 0.1 µT (1 mG ).

WebAn electromagnetic field (also EM field or EMF) is a classical (i.e. non-quantum) field produced by moving electric charges. [1] It is the field described by classical electrodynamics (a classical field theory) and is the classical counterpart to the quantized electromagnetic field tensor in quantum electrodynamics (a quantum field theory ). WebThe physics of traveling electromagnetic fields was worked out by Maxwell in 1873. He showed in a more general way than our derivation that electromagnetic waves always travel in free space with a speed given by Equation 16.18. If we evaluate the speed c = 1 √ε0μ0, we find that c = 1 √(8.85 × 10−12 C2 N · m2)(4π × 10−7T · m A) = 3.00 × 108m/s,
