draw magnetic field lines produced around a current carrying straight conductor passing through cardboard. how will the strength of the magnetic field change ,when the point where magnetic field is to be determined is moved away from the straight wire carrying constant current?justify your answre pleas
he direction of the magnetic lines of forces produced around a current carrying conductor passing through the axis of a cardboard as shown below, is given by Fleming's Right-Hand Thumb Rule also known as Maxwells corkscrew rule.
As the strength of magnetic field varies inversely with the square of the distance of the point from the elementary portion of the conductor carrying current so magnetic field strength will reduced at the point where the magnetic field is to be determined, is moved away from the straight wire carrying constant current.
