## What is Ampere circuital law

Ampere circuital law – After the discovery of Oersted and Biot-Savart, Ampere found a useful relation between magnetic field and electric current.     [ In the case of all basic laws of physics , Ampere’s law can’t be derived , its validity is based on the correctness of the result.] . According to Ampere circuital law […]

## MAGNETIC EFFECT OF CURRENT

Magnetic effect of current– If current flows through a conductor setup magnetic field around it is first observed by Oersted in 1820 . After that Biot-savart  established a formula for magnetic field due to small current carrying conductor. Direction of magnetic field can be found using right hand thumb rule . If current is flowing […]
