WebbInduced Emf and Induced Current There are a number of ways a magnetic field can be used to generate an electric current. It is the changing field that produces the current. So far we have dealt only with currents and magnetic fields which are constant in time, and we have shown that currents (i.e. moving charges) produce magnetic fields. Can magnetic … WebbAnd finally, when we calculated this, CNF induced here comes out to be 47104 0.2 in tow. 10 rich par, minus five volt. Or we can say this is 471 0.4 in tow. 10.
