... A planer loop consisting of four turns of wire, each of which encloses 200 cm 2, is oriented perpendicularly to a magnetic field that increases uniformly in magnitude form 10 mT to 25 mT in a time of 5.0 ms. That is the resulting induced current in the coil if the resistance of the coil is 5.0 Ω? ...

History of electromagnetic theory

For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
