A long wire is bent into a circular loop and long straight wires. On other sides, but there being no contact at the point P. If a current I enters at Q and leaves at R, the, the magnetic induction at point O :

A wire is bent in the form of a circular arc of radius r with a straight portion AB. If the current in the wire is i , then the magnetic induction at point O is

A wire is bent in the form of a circular arc of radius r with a straight portion AB. If the current in the wire is i , then the magnetic induction at point O is

A current I flows in a long straight wire (into the plane of the paper) with cross-section having the from of a circular are of radius R a shown in the figure. Find the magnetic induction at the point O .

A current I flows in a long straight wire (into the plane of the paper) with cross-section having the from of a circular are of radius R a shown in the figure. Find the magnetic induction at the point O .

A long current carrying wire is bent as shown. The magnetic field induction at O is

A steady current flows in a long wire. It is bent into a circular lopp of one turn and the magnetic field at the centre of the coil is B. If the same wire is bent into a circular loop of n turns, the magnetic field at the centre of the coil is

A steady current flows in a long wire. It is bent into a circular lopp of one turn and the magnetic field at the centre of the coil is B. If the same wire is bent into a circular loop of n turns, the magnetic field at the centre of the coil is

A uniform wire is bent into one turn circular loop and same wire is again bent in two circular loop. For the same current passed in both the cases compare the magnetic field induction at their centres.

Two inflinitely long wires carrying current I, are bent as shown in the figure. Find the magnetic induction at point C.
