$3\, A$ of current is flowing in a linear conductor having a length of $40\, cm$. The conductor is placed in a magnetic field of strength $500$ $gauss$ and makes an angle of $30^\circ $ with the direction of the field. It experiences a force of magnitude
A moving coil galvanometer has a coil with $175\, turns$ and area $1\, cm^2$ It uses a torsion band of torsion constant $10^{-6}\, N\, -m/rad$. The coil is placed in a magnetic field $B$ parallel to its plane. The coil deflects by $10$ for a current of $1\, mA$. The value of $B$ (in Tesla) is approximately
A particle of charge $q$ and mass $m$ is moving along the $x$ -axis with a velocity $v$ and enters a region of electric field $E$ and magnetic field $B$ as shown in figure below for which figure the net force on the charge may be zero
Two infinitely long parallel wires carry currents of magnitude $I_1$ and $I_2$ are at a distance $4 cm$ apart. The magnitude of the net magnetic field is found to reach a non-zero minimum value between the two wires and $1 \,cm$ away from the first wire. The ratio of the two currents and their mutual direction is
An infinitely long conductor $PQR$ is bent to form a right angle as shown. A current $I$ flows through $PQR$ The magnetic field due to this current at the point $M $ is $H_1$. Now another infinitely long straight conductor $QS$ is connected at $Q$ so that the current is $I/2$ in $QR$ as well as in $QS$, The current in $PQ$ remaining unchanged. The magnetic field at $M$ is now ${H_{2.}}$The ratio ${H_1}/{H_2}$ is given by
A rectangular coil (Dimension $5\,cm\times 2\,cm$ ) with $100\,turns,$ carrying a current of $3\,A$ in the clock-wise direction, is kept centered at the origin and in the $X-Z$ plane. A magnetic field of $1\,T$ is applied along $X-$ axis. If the coil is tilted through $45^o$ about $Z-$ axis, then the torque on the coil is.....$Nm$
The coil of a galvanometer consists of $100$ $turns$ and effective area of $1\, square-cm$. The restoring couple is ${10^{ - 8}}\,N - m/radian$. The magnetic field between the pole pieces is $5\, T$. The current sensitivity of this galvanometer will be
