Question

Write one properties of ferromagnetic substance

Answer 1

Answer:

Properties of ferromagnetic materials

• Permeability is greater than 1.
• Permeability is greater than 1.Magnetic susceptibility is large and positive.
• Permeability is greater than 1.Magnetic susceptibility is large and positive.Magnetic susceptibility decreases with the rise in temperature according to Curie-Weiss law.
• Permeability is greater than 1.Magnetic susceptibility is large and positive.Magnetic susceptibility decreases with the rise in temperature according to Curie-Weiss law.Ferromagnetism is the property of a material to be strongly attracted to a magnetic field and to become a powerful magnet.

Answer 2

• Atomic dipoles exists & are aligned in same direction in small volumes called domain.
• They are strongly attracted in external magnetic field.
• In non uniform field they seperately move from weak to strong field region.
• Magnetic field becomes very dense inside ferromagnetic substance.
• On increasing temperature, ferromagnetic property decreases At some point, the ferromagnetic material starts behaving like paramagnetic material this temperature is called Curie's temperature.
