The kinematic approximation becomes invalid when the magnetic field becomes strong enough to affect the fluid motions. In that case the velocity field becomes affected by the Lorentz force, and so the induction equation is no longer linear in the magnetic field. In most cases this leads to a quenching of the amplitude of the dynamo. Such dynamos are sometimes also referred to as hydromagnetic dynamos. Virtually all dynamos in astrophysics and geophysics are hydromagnet… WebbThe theoretical and experimental values can be compared using the X 2 method as follows: 𝑋 2 = ((22 𝑥 10−6)− ( 40 𝑥 10−6)) 2 (3543 𝑥 10−6) 2 + (1 𝑥 10 −6) 2 = 7. 62 𝑥 10−7< 3. … shannen dee williams villanova universityWebbThe field arising from magnetic materials in the Earth's crust varies on all spatial scales and is often referred to as the anomaly field.
