| magnetic force | a force produced when magnetic poles interact |
| magnetic field | the region around a magnet where the magnetic force is exerted |
| magnetic field lines | invisible lines that map out the magnetic field around a magnet |
| atom | the smallest particle of an element that has the properties of that element |
| nucleus | the center of the atom where you find the protons and the neutrons |
| proton | the positively charged particle of the atom found in the nucleus |
| electron | a negatively charged particle that is found outside the nucleus of the atom |
| magnetic domain | a region in which the magnetic fields of all the atoms are lined up in the same direction |
| ferromagnetic material | material that is strongly attracted to a magnet--containing iron |
| magnetic declination | the angle between the geographic north and the north to which a compass needle points |
| Van Allen belts | two doughnut shaped regions above Earth that contain electrons and protons traveling at high speeds |
