Theoritical value of earth magnetic field
WebbThe data were surveyed and gathered from final year diploma students of two fields of study (engineering, commerce) offered by POLISAS. A total of 100 questionnaires were distributed to the respondents but only 88 questionnaires were used in … 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…
