No. Date Physics. "Electro Magnetic Induction" Magnetic field + change. eMf /Current. two Related PhenoMera: Moving Conductor in B Field induces emf (clue magnetic face) Changing B field induces electric Field). Motionalery - eMF due to Magnetic Force on moving Conductor. ex: Conducting bar @ Constant speed U in unform B B V x Magnetic force on a charge in the Conductor: FB B F 50 pushes (+) 48 E point down Leads to charge Separation 11 IM E
No. Date Steady state reached when net force Is Zem P FB i Frety: FB -FF FE = 9 VB . qt E=Vb = O For bar w/leght induced emp is: E- AV = EL : VBL E = VBL Our Moving bar act just like a Vdltage Source/ Battery Source OF emf 10 Magnetic Force Created Tails: a close circuit by letting bar slide on Conducting x x R.
