What is the magnitude of magnetic field at the centre O of loop of radius (sqrt2) m made of uniform wire when a current of 1 A enters in the loop and is taken out of it by two long wires as shown in Fig.

What will be magnetic field at centre of current carrying circular loop of radius R?

The magnetic field at the centre of the circular loop as shown in Fig. when a single wire is bent to form a circular loop and also extends to form straight sections is

On meter length of wires carriers a constant current. The wire is bent to from a circular loop. The magnetic field at the centre of this loop is B . The same is now bent to form a circular loop of smaller radius to have four turns in the loop. The magnetic field at the centre of this loop B . The same is now bent to form a circular loop of smaller radius of have four turns in the loop. The magnetic field at the centre of this new loop is

The magnetic field at O due to current in the infinite wire forming a loop as a shown in Fig.

The figure shows a circular loop of radius a with two long parallel wires (numbered 1 and 2) all in the plane of the paper . The distance of each wire from the centre of the loop is d . The loop and the wire are carrying the same current I . The current in the loop is in the counterclockwise direction if seen from above. (q) The magnetic fields(B) at P due to the currents in the wires are in opposite directions. (r) There is no magnetic field at P . (s) The wires repel each other. (4) When d~~a but wires are not touching the loop , it is found that the net magnetic field on the axis of the loop at a height h above the loop is zero. In that case

A wire of length 'I' is bent into a circular loop of radius R and carries a current I. The magnetic field at the centre of the loop is 'B '. The same wire is now bent into a double loop. If both loops carry the same current I and it is in the same direction, the magnetic field at the centre of the double loop will be

A circular loop of radius a, carrying a current I, is placed in a tow dimensional magnetic field. The centre of the loop coincides with the centre of the filed The strenght of the magnetic field at the pariphery of the loop is B. find the magnetic force on the wire.

The figure shows a circular loop of radius a with two long parallel wires (numbered 1 and 2) all in the plane of the paper . The distance of each wire from the centre of the loop is d . The loop and the wire are carrying the same current I . The current in the loop is in the counterclockwise direction if seen from above. . (5) Consider dgtgta , and the loop is rotated about its diameter parallel to the wires by 30^(@) from the position shown in the figure. If the currents in the wire are in the opposite directions, the torque on the loop at its new position will be ( assume that the net field due to the wires is constant over the loop).
