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 ). WebOct 25, 2024 · 1. No Basically earths magnetic field is not a constant magnetic field like a bar magnet. It is more over dynamo effect. As like, earths molten core is moving and producing magnetic field. To any sorts of communication, we require fixed frequency of signal. Which will not be the case if you consider this dynamic system.

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, high five jumpers
