In this article, let us learn in detail about Ampere’s Law. What is Ampere’s Law? According to Ampere’s law, magnetic fields are related to the electric current produced in them. The law specifies the magnetic field that is associated with a given current or vice-versa, provided that the electric field doesn’t change with time.

According to the equation, the magnetic field lowers in magnitude as we move wider. Hence, Ampere’s law can be applied to calculate the extent of the magnetic field surrounding the wire. The field H is a vector field which reveals that each region has both a direction and a magnitude.

André Ampère formulated a law based on Oersted’s as well as his own experimental studies. This law can be regarded as an s alternative expression of Biot-savert’s law which also relates the magnetic field and current produced. But it needed an exclusive calculation of the curl of B .
