IB Physics: Magnetism and Electromagnetic Induction. - ppt video online download: Magnetite: From Magnesia (Greece). Formula: Fe3O4. Description: Dark grey, slightly shiny. Magnetite is naturally magnetic. It is also called Lodestone. In Middle Ages, pilots were called lodesmen. The lodestar is the Polar star, the leading star by which mariners are guided. The name probably comes from Magnesia, but there is a fable of Magnes, a Greek shepherd, who discovered magnetite when the nails in his shoes stuck to the ground!

5.3 Magnetism IB Physics. - ppt video online download: Magnets and magnetic fields Draw the pattern of magnetic field lines of an isolated bar magnet Draw the magnetic field pattern for the Earth. Students should understand that the Earth’s magnetic field is similar to that of a bar magnet with a south magnetic pole near the geographic north pole, and that an isolated suspended magnet will orientate itself along the Earth’s magnetic field with its magnetic north pole directed towards the Earth’s geographic north pole. They should recognize the compass as one example of a suspended bar magnet Draw and annotate magnetic fields due to currents. These include fields around a straight wire, a flat circular coil and a solenoid. Students should recognize that the magnetic field pattern of a solenoid is similar to that of a bar magnet.
