Magnetic field due to currentHard
Question
Relative permittivity and permeability of a material are εr and μr, respectively. Which of the following values of these quantities are allowed for a diamagnetic material?
Options
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
Solution
Permittivity: An electric field causes some materials to polarize.
Permeability: A magnetic field will cause a magnet to align with it
