A moving charge produces
-
Neither electric field nor magnetic field
-
Electro-static field only
-
Magnetic field only
-
Both magnetic and electro-static field
A charged particle produces an electric field around it independent of its motion. But when it is at rest, it doesn't produce a magnetic field.
The magnetic lines of force due to straight current carrying conductor are:
-
circular lines
-
straight lines
-
concentric lines
-
elliptical lines
SI unit of permittivity of free space is:
-
Farad
-
Weber
-
${ C }^{ 2 }{ N }^{ -1 }{ m }^{ -2 }$
-
${ C }^{ 2 }{ N }^{ -1 }{ m }^{ -1 }$
Coulombic force between two charges is given by
F=1/4π€ (q'.q″/r²)
From here, the SI UNIT of permittivity comes out is
= coulomb²/Newton-meter²
C²/N-m²
If an electron is moving with velocity $\bar{v}$ produces a magnetic field $\bar{B}$, then
-
the direction of field $\bar{B}$ will be same as the direction of velocity $\bar{v}$
-
the direction of field $\bar{B}$ will be opposite as the direction of velocity $\bar{v}$
-
the direction of field $\bar{B}$ will be perpendicular as the direction of velocity $\bar{v}$
-
the direction of field $\bar{B}$ does not depend upon the direction of velocity $\bar{v}$
According to Biot-Savart's law, the magnetic field
$\displaystyle \overset{\rightarrow}{B} = \frac{\mu _o}{4 \pi} . \frac{q (\overset{\rightarrow}{v} \times \overset{\rightarrow}{r} ) }{r^3}$
The direction of $\overset{\rightarrow}{B}$ will be along $\overset{\rightarrow}{v} \times \overset{\rightarrow}{r}$ i.e. perpendicular to the plane containing $\overset{\rightarrow}{v}$ and $\overset{\rightarrow}{r}$.
