For the students, Ampere’s Law is one of the useful Laws which relates the net Magnetic field along the closed-loop to the Electric current which passes through the loop. The Law was discovered by André-Marie Ampere in 1826. The expression for the relation between the Magnetic field and the current which produces it is termed Ampere’s Law.

### What is amperes law?

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.

### How can amperes law be used to calculate the magnetic field?

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.
