Question

explain magnetic field due to current through a circular loop

Answer 1

Magnetic field lines due to a current carrying conductor . Magnetic field lines dur to circular current carrying conductor are in the form of concentric circles on both the sides. ▶As we know that towards the centre of loop the field lime become straight . ➡ Magnetic field lines due to current carrying solenoid .

Answer 2

The magnetic field produced by a current carrying straight wire depends inversely on the distance from it . similar at every point of current carrying circular loop the concentric circle representing the magnetic field around it would become larger and larger as we move away from the wire . by the time we reach at the centre of the circular loop the arcs of these big circle would appear as straight lines. Every point on the wire carrying current would give rise to the magnetic field appearing as straight lines at the center of loop. By applying at right hand rule, it is easy to check that every section of the wire contributes to magnetic field lines in the same direction within the loop.
