TOPIC 4.4: ELECTROMAGNETISM
... the principle that moving charges generate a magnetic field. This magnetic field is the same force that is demonstrated by permanent magnets. The domain theory should be related to the motion of the electron. Demonstration Hans Christian Oersted’s discovery of electromagnetism can be demonstrated by ...

magnetic field
... Since a current carrying wire has a magnetic field around it, an external magnetic field around the wire can cause the wire to move. This is because of the attraction or repulsion of the two magnetic fields (the one around the wire and the external one). ...

Physics of Ballet Dancing
... Friction is very important in dancing. To increase friction many ballet dancers use a substance called Rosin. Rosin has a high coefficient of kinetic friction but a significantly smaller dynamic coefficient. This means that if the foot is stationary on the floor a large horizontal frictional force i ...
