The phenomenon of electromagnetic induction is:

The following diagram shows two straight wires carrying current. Copy the diagram and draw the pattern of lines of force around them and mark their directions.

The magnitude of an $AC$ voltage used in other countries like America $(USA)$ is $.........$ and its frequency is $.......$.

The induced potential difference produced in a coil when a magnet is inserted into it does not depend upon:

In order to find the force experienced by a current-carrying conductor,we can use Maxwell's corkscrew rule.

$A$ circular loop placed in a plane perpendicular to the plane of paper carries a current when the key is $ON$. The current as seen from points $A$ and $B$ (in the plane of paper and on the axis of the coil) is anti-clockwise and clockwise respectively. The magnetic field lines point from $B$ to $A$. The $N-$ pole of the resultant magnet is on the face close to
