Ferromagnetic materials are strongly attracted to magnetic fields and can be permanently magnetized. Common examples include iron, cobalt, nickel, and their alloys. Silver is a diamagnetic material, which means it is weakly repelled by a magnetic field. Ferric chloride is a paramagnetic material, which is weakly attracted by a magnetic field. Neither diamagnetic nor paramagnetic materials are classified as ferromagnetic.
Which one of the following is not a ferromagnetic material?
