similar poles repel similar - - (2 negative)and ++ (2 positive)
opposite poles attract (+ - )
the general direction is from the north end to the south
Magnetic Field
distribution of a magnetic force in the region of a magnet
Earth's magnetic field is produced because of a flow of hot liquid metals inside Earth
Ferromagnetic metals have atomic structure that seems to make them strongly magnetic
Domain Theory of magnets : Large magnets are made up of small and rotating magnets, called dipoles
Oersted's Principle : Charge moving through a conductor produces a circular magnetic field around the conductor
First right-hand rule for conductors
Grasp conductor with the thumb of the right hand pointing in the direction of current. The finger tips is direction of the magnetic field around the conductor. (1)

Second right-hand rule for coils (1) >>>
Grasp the coiled conductor with the right hand such that the four fingers point to the current flow. The thumb points in the direction of the magnetic field within the coil. Outside the coil, the thumb represents the north.
