Question

Relative permittivity and permeability of a material εr and μr , respectively. Which of the following values of these quantities are allowed for a diamagnetic material? (A) εr = 0.5 , μr = 1.5 (B) εr = 1.5 , μr = 0.5 (C) εr = 0.5 , μr = 0.5  (D) εr = 1.5 , μr = 1.5

For a diamagnetic material, the value of μr is less than one. For any material, the value of ∈r is always greater than 1.

Q. Relative permittivity and permeability of a material $ε_{r}$ and $μ_{r}$ , respectively. Which of the following values of these quantities are allowed for a diamagnetic material?

$ε_{r} = 0.5, μ_{r} = 1.5$

$ε_{r} = 1.5, μ_{r} = 0.5$

$ε_{r} = 0.5, μ_{r} = 0.5$

$ε_{r} = 1.5, μ_{r} = 1.5$

For a diamagnetic material, the value of $μ_{r}$ is less than one. For any material, the value of $\in_{r}$ is always greater than 1.

Q. Relative permittivity and permeability of a material εr​ and μr​ , respectively. Which of the following values of these quantities are allowed for a diamagnetic material?

εr​=0.5,μr​=1.5

εr​=1.5,μr​=0.5

εr​=0.5,μr​=0.5

εr​=1.5,μr​=1.5
