The magnetic moment of an electron $(e)$ revolving in an orbit around nucleus with an orbital angular momentum is given by :
A$\vec{\mu}_{ L }=\frac{ e \overrightarrow{ L }}{2 m }$
B$\vec{\mu}_{ L }=-\frac{ e \overrightarrow{ L }}{2 m }$
C$\vec{\mu}_{1}=-\frac{e \vec{L}}{m}$
D$\vec{\mu}_{1}=\frac{2 e \overrightarrow{ L }}{ m }$

B$\vec{\mu}_{ L }=-\frac{ e \overrightarrow{ L }}{2 m }$
b Ratio of magnetic moment and angular momentum
$\frac{\vec{\mu}}{\vec{L}}=\frac{q}{2 m}$
For $e^{-}$

$STATEMENT-1$ A vertical iron rod has a coil of wire wound over it at the bottom end. An alternating current flows in the coil. The rod goes through a conducting ring as shown in the figure. The ring can float at a certain height above the coil. Because
$STATEMENT- 2$ In the above situation, a current is induced in the ring which interacts with the horizontal component of the magnetic field to produce an average force in the upward direction.
A particle of charge $q$ and velocity $v$ passes undeflected through a space with non-zero electric field $E$ and magnetic field $B$. The undeflecting conditions will hold if.
If current flowing through shell of previous objective is equal to $i$, then energy density at a point distance $2R$ from axis of the shell varies according to the graph
A long solenoid carrying a current produces a magnetic field $B$ along its axis. If the current is doubled and the number of turns per cm is halved, the new value of the magnetic field is
A semi circular current carrying wire having radius $R$ is placed in $x-y$ plane with its centre at origin $‘O’$. There is non-uniform magnetic $\vec B = \frac{{{B_o}x}}{{2R}}\hat k$ (here $B_o$ is + $ve$ constant) is existing in the region. The magnetic force acting on semi circular wire will be along
A uniform magnetic field $\vec B = \left( {3\hat i + 4\hat j + \hat k} \right)$ exists in region of space. A semicircular wire of radius $1\,m$ carrying current $1\,A$ having its centre at $(2, 2, 0)$ is placed in $x-y$ plane as shown in figure. The force on semicircular wire will be
Three long, straight and parallel wires carrying currents are arranged as shown in the figure. The wire $C$ which carries a current of $5.0\, amp$ is so placed that it experiences no force. The distance of wire $C$ from wire $D$ is then
A moving coil galvanometer has $150$ equal divisions. Its current sensitivity is $10$ divisions per milliampere and voltage sensitivity is $2$ divisions per millivolt. In order that each division reads $1\, volt$, the resistance in $ohms$ needed to be connected in series with the coil will be
In figure two parallel infinitely long current carrying wires are shown. If resultant magnetic field at point $A$ is zero. Then determine current $I.$ (in $A$)
