PHY2061 R. D. Field Department of Physics chp34_4.doc University of Florida Faraday’s Law of Induction Magnetic Flux: The magnetic flux through the surface S is defined by, Φ B S Bd A =⋅ r r . In the simple case where B is constant and normal to the surface then Φ B = BA . The units for magnetic flux are webbers (1 Wb = 1 Tm 2 ). Rate of Change of the Magnetic Flux through Moving Loop: The change in magnetic flux , d Φ B , in a time dt through the moving loop is, d Φ B = B 2 dA-B 1 dA, with dA = vdtL so that
