... False: That formula is for an infinitely long straight wire, with no other wires nearby. It doesn't apply here because the other side of the U breaks the symmetry of the situation. In this messy situation, with a U-shaped wire, Ampere's Law is true, but not useful since the integral is very messy. T ...

... To calculate the electric field from many charges, we use SUPERPOSITION: If we have a discrete collection of point charges, figure out the electric field vector from each charge using Coulomb's Law and then add all the vectors. If we have a continuous distribution of charge, we divide up the d ...

... The reason alternating current is used for the transmission of power to our homes is due to the ease in stepping up or down voltage by using transformers. Since resistance depends upon length, transmitting energy long distances would result in a significant amount of energy lost in heating of the tr ...

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.
