Module 3. Electrical fundamentals

Glass is an example of a

  • diamagnetic material.
  • coercive material.
  • paramagnetic material.

Explanation

Glass has no unpaired electron spins, so it is weakly repelled by a magnetic field and has a relative permeability slightly less than one, the defining trait of a diamagnetic material. Paramagnetic materials are weakly attracted (permeability just above one), so that option does not fit glass.

thomasloca asking:

In another questions glass is said to be paramagnetic. What's the correct one?!
Thanks
