تعريف المغناطيس. ما هو المغناطيس ؟ تعريف وأمثلة

- magnetism used to levitate objects• - group of six magnets laid in alternating arrangement of poles• - a mechanism for measuring the response of materials to an applied field• record data on a thin magnetic coating Effect of a magnet on the domains
Magnetic domains in ferromagnetic material - group of four magnets laid out so that the dipole terms cancel• - a magnet constructed to create a homogeneous magnetic field over some distance•

مغناطيس(المغناطيس الدائم)

- the general study of magnetic phenomena• - materials that are repelled by magnetic fields• - magnets produced by electric current• - a configuration of magnets that focuses the field• - static magnetic levitation under gravity is impossible except for diamagnets or with control systems• - 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.
