Microscopic areas of atoms where the magnetic fields are aligned.
A naturally magnetic class of materials where the magnetic domains are ordered and do not cancel out.
Lines showing the shape and exent of a magnetic field around a permanent magnet or a moving charged object. To signify a field coming directly out of the plane of a page, dots are used. To signify a field going directly into the page, an X is used.
Right Hand Rule. RHR:
- The fingers extend or curl in the direction of the magnetic field.
- The outstretched thumb points in the direction of conventional current, or the direction of a positively charged moving particle.
- A line perpendicular to the palm indicates the direction of the magnetic force.
A device that magnetically separates charged ions according to their mass. A magnetic field is used to accomplish this separation.
