| - the branch of physics related to magnetic and electric fields• When a domain contains too many molecules, it becomes unstable and divides into two domains aligned in opposite directions so that they stick together more stably as shown at the right | - a theoretical source of magnetism that has never been found in real life |
|---|---|
| - magnetism used to levitate objects• - group of four magnets laid out so that the dipole terms cancel• record data on a thin magnetic coating | - group of six magnets laid in alternating arrangement of poles• Effect of a magnet on the domains |
- a mechanism for measuring the response of materials to an applied field• - the general study of magnetic phenomena• - a magnet constructed to create a homogeneous magnetic field over some distance• - static magnetic levitation under gravity is impossible except for diamagnets or with control systems•.
