Question

Magnetic susceptibility is positive and small for __
A. Silver
B. Platinum
C. Mercury
D. Sodium chloride

Answer 1

Hint: Attractive materials which line up with the attractive field are known as paramagnetic materials. Attractive weakness is χ>0 which implies it's anything but a little sure incentive for paramagnetic materials. These materials are temperature subordinate and are affected week after week by magnets with relative porousness 1.00001 to 1.003.

Complete step-by-step solution:
Attractive materials which adjust against the attractive field are known as diamagnetic materials. Attractive weakness is χ<0 which implies it's anything but a negative incentive for diamagnetic material. These materials are repulsed by the magnets and they move from a more grounded field to a more vulnerable field. These materials are independent of temperature. As these materials charge the other way, they do have a modest quantity of polarization power.
Attractive materials that are profoundly charged in an attractive field are known as ferromagnetic materials. These are profoundly drawn in by the magnets and move from more vulnerable fields to more grounded fields. Ferromagnetic materials don't have a steady relative porousness and differ from 1000 to 100000. Attractive weakness is exceptionally high and positive and relies upon the applied field. Iron, cobalt, nickel, and their composites are instances of ferromagnetic materials.
The numerical meaning of attractive vulnerability is the proportion of polarization to applied charging field power.
This is a dimensionless quantity. [χ=M/H]
 Were,
χ: magnetic susceptibility
M: magnetization
H: field intensity

Note:Attractive helplessness is a dimensionless proportionality steady that demonstrates the level of polarization of a material in light of an applied attractive field. It is brought about by the collaborations of electrons and cores with the remotely applied attractive field.
