area surrounding a magnet through which magnetic force is exerted and that extends between a magnets north and south poles
group of atoms whose field points are in the same direction
a magnetic field surrounding earth that deflects most of the charged particles flowing from the sun
magnet created by wrapping a current carrying wire around an iron core
device that transforms electrical energy into kinetic energy
southern and northern lights that appear when charged particles trapped in the magnetosphere collide with earths atmosphere above the poles
device that uses a magnetic field to turn kinetic energy into electrical energy and can produce direct current and alternating current
electrical current that changes its direction many times a second
semiconductor device that can amplify the strength of an electric signal or act as a electronic switch
