Magnetism
If the magnetizing field on a ferromagnetic material is increased, its permeability.
Two substances A and B have their relative permeabilities slightly greater and slightly less than 1 respectively. What do you conclude about A and B as far as their magnetic materials are concerned?
The material which has relative permeabilities slightly greater one are paramagnetic whereas the material which has relative permeabilities slightly lesser than one are diamagnetic.
A $$\rightarrow$$ Paramagnetic
B $$\rightarrow$$ Diamagnetic
If the magnetizing field on a ferromagnetic material is increased, its permeability.
An iron rod is placed parallel to the magnetic field of intensity 2000 A/m. The magnetic flux through the rod is $$6 \times 10^{-4} Wb$$ and its cross-sectional area is 3 cm$$^2$$. The magnetic permeability of the rod in $$\dfrac{Wb}{A- m}$$ is:
The rising and setting of sun appear red because of :
Let $$[\varepsilon_o]$$ denote the dimensional formula of the permittivity of the vacuum, and $$[\mu_o]$$ that of the permeability of the vacuum. If M$$=$$mass, L$$=$$length, T$$=$$time and I$$=$$ electric current.
If $$\mu _{r}$$ be the relative permeability and $$\varepsilon _{r}$$ be the relative dielectric constant of a medium, its refractive index is:
The dimension of $$\sqrt{\dfrac{\mu }{\epsilon }}$$ where $$\mu$$ is permeability & $$\epsilon$$ is permittivity is same as :
The value of $$\mu_o$$ is __________.
In terms of potential difference V; electric current I, permittivity $$\varepsilon_0$$, permeability $$\mu_0$$ and speed of light c, the dimensionally correct equation(s) is(are).
