... This experiment was named after Hans Christian Øersted (14 August 1777 – 9 March 1851) who was a Danish chemist. While preparing for an evening lecture on 21 April 1820, Oersted developed an experiment which provided evidence that surprised him. As he was setting up his materials, he noticed a compa ...

... Note that this function is strongly dependent on the perimeter and weakly dependent on loop area and wire radius. For this reason, the inductance of complicated shapes can often be well approximated by a simpler shape with the same perimeter and/or area. Conductors can be replaced by filaments in or ...

... • The earth's magnetic field is similar to that of a bar magnet tilted 11 degrees from the spin axis of the earth. • The problem with that picture is that the Curie temperature of iron is about 770 C . • The earth's core is hotter than that and therefore not magnetic. So how did the earth get its ma ...
