... With leading questions, get to a summary of what they have learned from their experiment. They will come up with lots of things, write them all on the board. The ones we need right now: 1. An electric current flowing through a wire creates a magnetic field. 2. The direction in which the current fl ...

... In 1819 the Danish physicist Hans Christian Oersted discovered that an electric current flowing through a wire deflected a compass needle. A year later the Frenchman François Arago found that a wire carrying an electric current acted as a magnet and could attract iron filings. Soon his compatriot An ...

Flux of a vector (and the notion of `solid angle`) - Rose
... You already learned that for a point charge +q the electric field E points directly away from the charge, and you may recall from Gauss's law that the flux of electric field for a surface S which encloses the charge is given by the enclosed charge divided by o. Since k = 1/(4o) we can write this ...
