PHY2061 R. D. Field Department of Physics chp34_3.doc University of Florida Electromagnetic Induction Conducting Loop Moving through a Uniform Magnetic Field: The magnetic force on the charge q in the loop on side 1 is, r r r Fq v B B 11 , and for a charge q on side 2 to it is, r r r v B B 22 . However, because the magnetic field is uniform, rr BB 12 = , and the induced EMF’s on side 1 and side 2 are equal, ε 1 = ε 2 , and the net EMF around the loop ( counterclockwise ) is zero, εε ε =⋅ = = 1 0 q Fd l B Loop r r .
