-
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
-
ferrimagnetism
a phenomenon in ferrites where there can be incomplete cancellation of antiferromagnetic arranged spins giving a net magnetic moment
