State and explain Biot-Savart’s law In this topic we will discuss about Biot-savart’s law and magnetic field at a point due to finite current carrying wire or conductor. Biot- Savart law – Biot-Savart’s law explain the magnetic field due to small current carrying element As we know , whenever the current passes through a conductor… Continue reading Biot-Savart’s law

## 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… Continue reading What is 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… Continue reading MAGNETIC EFFECT OF CURRENT
