Question

Difference between paramagnetism and diamagnetism

Answer 1

Answer:

Explanation:-

The term paramagnetic refers to the attraction of a material to an external magnetic field while the term diamagnetic refers to the repulsion of a material from an external magnetic field. This is mainly because the paramagnetic materials have unpaired electrons whereas diamagnetic materials have none of their electrons unpaired. This is the fundamental difference between paramagnetic and diamagnetic materials.

Another important difference between paramagnetic and diamagnetic materials is that the magnetic field created by paramagnetic materials is in the direction of the external magnetic field while the magnetic field created by diamagnetic materials is opposing in a direction to the external magnetic field.

Answer 2

Differentiate between

Paramagnetic

• The term paramagnetic refers to the attraction of a material to an external magnetic field.
• Materials have at least one unpaired electron in the system.
• Magnetic field created is in the direction of the external magnetic field.
• Stronger magnetic behaviour exhibited only by selective materials.
• Magnetic susceptibility ( x ) is +ve.
• Relative permeability is +ve and greater than one.
• Ex: Aluminium, platinum, TiO, O2.

Diamagnetic

• The term diamagnetic refers to the repulsion of a material from an external magnetic field.
• Materials have no unpaired electrons.
• Magnetic field created is opposing in a direction of the external magnetic field.
• Weak magnetic behaviour generally is shown by all materials and easily suppressed in the presence of stronger magnetic properties.
• Magnetic susceptibility is negative.
• Relative permeability is +ve but less than one.
• Ex: Copper, Gold, NaCl, Zn²+
