Magnetism Question 283
Question: 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?
Options:
A) $ {\varepsilon _{r}}=0.5,,,,{\mu _{r}}=1.5 $
B) $ {\varepsilon _{r}}=1.5,,,,{\mu _{r}}=0.5 $
C) $ {\varepsilon _{r}}=0.5,,,,{\mu _{r}}=0.5 $
D) $ {\varepsilon _{r}}=1.5,,,,{\mu _{r}}=1.5 $
Show Answer
Answer:
Correct Answer: B
Solution:
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.
