Meaning of MAGNETISM in English



Phenomenon associated with magnetic fields , the effects of such fields, and the motion of electric charges .

Some types of magnetism are diamagnetism , paramagnetism , ferromagnetism , and ferrimagnetism . Magnetic fields exert forces on moving electric charges . The effects of such forces are evident in the deflection of an electron beam in a cathode-ray tube and the motor force on a current-carrying conductor . Other applications of magnetism range from the simple magnetic door catch to medical imaging devices and electromagnets used in high-energy particle accelerators .
