NEET2018PhysicsMagnetic Properties of MatterActual
A paramagnetic substance of susceptibility 3 10⁻⁴ is placed in a magnetising field of 4 10⁻⁴ ~A ~m ⁻¹ . Then the intensity of magnetisation in the units of A m ⁻¹ is
Options
- A1.33 10^8
- B0.75 10⁻⁸
- C12 10⁻⁸
- D14 10⁻⁸
Correct answer
C. 12 10⁻⁸
Step-by-step solution
aligned I & = H= (4 10⁻⁴ ) (3 10⁻⁴ ) & =12 10⁻⁸ ~A ~m ⁻¹ aligned
