The north pole of one magnet is always attracted to the south pole of other magnet and … The magnetic field lines are repelled or expelled by diamagnetic materials when placed in a magnetic field. (8) Magnetic Induction : A magnet attracts certain other substances through the phenomenon of magnetic induction i.e., by inducing opposite pole in a magnetic material on the side facing it as shown in fig. Some of the properties of solids which are useful in electronic and magnetic devices such as, transistor, computers, and telephones etc., are summarised below, (1) Electrical properties : Solids are classified into following classes depending on the extent of conducting nature. This property of the materials is called antiferromagnetism and antiferromagnetic materials are called the materials which exhibit this property. Magnetic flux:- Magnetic flux lined with the surface is defined as the product of area and component of B perpendicular that area.. and?
