MAGNETISM

MAGNETISM. Materials. Only iron, steel, nickel and cobalt are magnetic. Bar magnets have to be made using one of these substances. The metals affected by magnetism consist of tiny regions called 'Domains' which behave like tiny magnets.

Field Around Magnet

Field Around Magnet. Use a compass to map the direction of the magnetic field surrounding a magnet. White board your results. In particular: how does the strength of the field vary with distance from the wire? how does the field direction relate to the poles of the magnet?.

Force on a Moving Charge

A charged particle experiences a force when moving perpendicular to a magnetic field. Force on a Moving Charge. F=qvB sin ?. q = the amount of charge in motion in the magnetic field v = the velocity the charge in the magnetic field B = the magnetic field strength
