Is Lithium Magnetic or Non-magnetic?
Lithium attracts magnets. It is slightly more susceptible to magnetic fields than usual. Lithium has a weak attraction for an external magnetic field. However, lithium loses its magnetic properties when you remove the external field. Thermal motion causes the electron spins of lithium to become random, making lithium lose its magnetic properties.
