magnetism

Noun
  1. Attraction for iron;
    Associated with electric currents as well as magnets;
    Characterized by fields of force (synset 111499458)
    tells us about: attractive - having the properties of a magnet; the ability to draw or pull
    is a type of: attraction, attractive force - the force by which one object attracts another
    subtypes:
    • electromagnetism - magnetism produced by an electric current
    • antiferromagnetism - magnetic field creates parallel but opposing spins; varies with temperature
    • diamagnetism - phenomenon exhibited by materials like copper or bismuth that become magnetized in a magnetic field with a polarity opposite to the magnetic force; unlike iron they are slightly repelled by a magnet
    • ferromagnetism - phenomenon exhibited by materials like iron (nickel or cobalt) that become magnetized in a magnetic field and retain their magnetism when the field is removed
    • paramagnetism - materials like aluminum or platinum become magnetized in a magnetic field but it disappears when the field is removed
    same as: magnetic attraction, magnetic force
  2. The branch of science that studies magnetism (synset 106130376)
    is a type of: geophysical science, geophysics - geology that uses physical principles to study properties of the earth
    same as: magnetics
