Relative permittivity and permeability of a material $\varepsilon_r$ and $\mu_r$ , respectively. Which of the following values of these quantities are allowed for a diamagnetic material?
Updated On: Jul 7, 2022
- $\varepsilon_r = 0.5 , \mu_r = 1.5$
- $\varepsilon_r = 1.5 , \mu_r = 0.5$
- $\varepsilon_r = 0.5 , \mu_r = 0.5 $
- $\varepsilon_r = 1.5 , \mu_r = 1.5$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
For a diamagnetic material, the value of $\mu_r$ is less than one. For any material, the value of $\in_r$ is always greater than 1.

Osmosis
Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.
There are three different types of solutions:
- Isotonic Solution is one that has the same concentration of solutes both inside and outside the cell.
- Hypertonic solution is one that has a higher solute concentration outside the cell than inside.
- Hypotonic solution is one that has a higher solute concentration inside the cell than outside.
