Mass Spectrometer
Mass spectrometers use electric or magnetic fields to identify different materials.
Ferromagnetism
Ferromagnetism is the property of certain materials that enables them to form magnets and be attracted to magnets.
Paramagnetism and Diamagnetism
Paramagnetism is the attraction of material while in a magnetic field, and diamagnetism is the repulsion of magnetic fields.
Solenoids, Current Loops, and Electromagnets
Solenoids are loops of wire around a metallic core, and can be used to create controlled magnetic fields.
