Magnetic Materials

3. Materials which are capable to being
magnet in magnetic field are called as
magnetic materials.
Metals like :
iron,
nickel,
cobalt and their compounds and alloys
are magnetic in nature.
What Materials are Magnetic?

5. Magnetic materials can be classified in two types.
Soft magnetic materials: These materials do not have
permanent magnetism and lose their magnetism quickly in
the absence of magnetic field. They form temporary magnets
and also known as electromagnet. The best examples of soft
magnet are iron-silicon alloys, nickel-iron alloy and iron.
Hard magnetic materials: These magnetic materials retain
their magnetism in absence of magnetic field and also known
as permanent magnets. Alloys composed of iron, cobalt and
aluminum are generally acted as hard magnetic materials.

7. On the basis of response in magnetic field, magnetic material can be classified in
five types.
Diamagnetic materials: These materials have a weak, negative
susceptibility to magnetic fields. diamagnetic material are copper, silver, and
gold.
Paramagnetism: They have a small, positive susceptibility to magnetic
fields and slightly attracted by a magnetic field.
Magnesium, molybdenum, lithium, and tantalum are examples of paramagnetic
materials.
Ferromagnetism: They have a large, positive susceptibility to an external
magnetic field and exhibit a strong attraction to magnetic fields.
 Ferrimagnetism: In such materials, the electron spins are orientated
anti parallel to one another but, due to an inequality in the number of spins in
each orientation, there exists an overall magnetic moment.
Antiferromagnetism: They have unpaired electrons which are line up
opposite of one another and have a zero magnetic moment.
