Alternating current
... The generation of a current by a changing magnetic field is electromagnetic induction. • Working independently in 1831, Michael Faraday in Britain and Joseph Henry in the United States both found that moving a loop of wire through a magnetic field caused an electric current to flow in the wire. • Th ...

... was generated automatically by using free tetrahedral elements under Comsol. The nine elements constituting the probe-coil setup are meshed using the same element type; the maximum size was fixed at 20mm for the plate and 10mm for the coils. As the excitation coils are coupled to the test specimen t ...
