Question

If the magnetic dipole moment of an atom of diamagnetic material, paramagnetic material and ferromagnetic material are denoted ny μd, μp and μf respectively, then (A) μ p =0 and μ f ≠ 0 (B) μ d ≡ 0 and μ p =0 (C) μ d ≠ 0 and μ f ≠ 0 (D) μ d =0 and μ p = 0

Magnetic moment of ferromagnetic material

μ_{f}

is non-zero always.
Under application of external magnetic field, the paramagnetic material has all the magnetic moments aligned giving off

μ_{p} \equiv 0

.

However the magnetic moments of atoms in diamagnetic material cancels out resulting in

μ_{d} = 0

Q. If the magnetic dipole moment of an atom of diamagnetic material, paramagnetic material and ferromagnetic material are denoted ny $μ_{d}, μ_{p}$ and $μ_{f}$ respectively, then

$μ_{p} = 0$ and $μ_{f} \neq = 0$

$μ_{d} \equiv 0$ and $μ_{p} = 0$

$μ_{d} \neq = 0$ and $μ_{f} \neq = 0$

$μ_{d} = 0$ and $μ_{p} = 0$

Q. If the magnetic dipole moment of an atom of diamagnetic material, paramagnetic material and ferromagnetic material are denoted ny μd​,μp​ and μf​ respectively, then

μp​=0 and μf​=0

μd​≡0 and μp​=0

μd​=0 and μf​=0

μd​=0 and μp​=0

Magnetic moment of ferromagnetic material μf​ is non-zero always. Under application of external magnetic field, the paramagnetic material has all the magnetic moments aligned giving off μp​≡0. However the magnetic moments of atoms in diamagnetic material cancels out resulting in μd​=0

Q. If the magnetic dipole moment of an atom of diamagnetic material, paramagnetic material and ferromagnetic material are denoted ny $μ_{d}, μ_{p}$ and $μ_{f}$ respectively, then

$μ_{p} = 0$ and $μ_{f} \neq = 0$

$μ_{d} \equiv 0$ and $μ_{p} = 0$

$μ_{d} \neq = 0$ and $μ_{f} \neq = 0$

$μ_{d} = 0$ and $μ_{p} = 0$
