You place a substance in an external magnetic field and find that it is attracted to the field but only to a limited degree because of thermal agitation effects which do not permit atomic dipoles to align completely with the field.You know,therefore,that this substance is
A)diamagnetic
B)paramagnetic
C)permamagnetic
D)ferromagnetic
E)antimagnetic

Question

Quizplus · Accepted Answer

Diamagnetic materials are repelled by magnetic fields and do not exhibit any attraction to the field. Ferromagnetic and permamagnetic materials are strongly attracted to magnetic fields and will align their atomic dipoles completely with the field, resulting in a much stronger attraction compared to what is described in the question. Antimagnetic is not a recognized term in physics. Paramagnetic materials are attracted to magnetic fields but only to a limited degree due to thermal agitation effects that prevent complete alignment of atomic dipoles with the field. Therefore, the substance described in the question is most likely paramagnetic.
