A straight current carrying conductor is kept along the axis of circular loop carrying current. The force exerted by the straight conductor on the loop is :

$X$ and $Y$ are wires carrying electric currents which are perpendicular to the page and $A, B$ and $C$ are the three compasses as shown in figure. Which of the following statements is correct regarding magnitude and direction of current?

A small conducting rod of length $l$, moves with a uniform velocity $v$ in a uniform magnetic field $\mathrm{B}$ as shown in figure.

Consider the following statements and select the correct option which correctly identifies true $\left(\mathrm{T}\right)$ and false $\left(\mathrm{F}\right)$.

$\left(\mathrm{i}\right)$ Magnetic field lines do not intersect because they always travel parallel to each other in North to South direction.
$\left(\mathrm{ii}\right)$ When a current flows through a straight copper conductor, it gets permanently magnetised.
$\left(\mathrm{iii}\right)$ The strength of magnetic field at the centre of a circular coil is inversely proportional to the radius of coil.
 

Current is passed through the circular loop as shown in figure. What is the direction of magnetic field at $X$ and $Y$?

A straight wire is placed between two poles of a magnet as shown in figure. If an alternating current passing through a wire then wire will

A wire is placed between the magnetic poles as shown in figure. In which direction does a force act on the wire?

Consider the arrangement shown in figure in which the North pole of a magnet is moved away from a thick conducting loop containing capacitor. Then excess positive charge will arrive on

An electric current passes through a straight wire. If magnetic compasses are placed at the points $X$ and $Y$ as shown. Then,
