Ampers circular law

The line integral of the magnetic field around any closed path is equal to \mu_{o} times the current enclosed by the path.

\oint B.dl=\mu_{o}I\; enclosed

Consider an infinitely long straight wire carrying current I.

The Amperian loop is a circle

\oint B.dl=\mu_{o}I

B\times 2\pi r= \mu_{o}I

B= \frac{\mu_{o}I}{2\pi r}

is the magnitude of the magnetic field due to straight infinite current-carrying wire at a distance r from it.

\rightarrow magnetic field lines forms closed loops.

\rightarrow Electric field lines originate from positive charge and end at a negative charge.
