Answer 2

Answer:

Given below is the unit

Explanation:

JC-1

The unit is ampere, volt

Ampère's circuital law, which should not be confused with Ampère's force law,[1] connects the integrated magnetic field around a closed loop to the electric current flowing through the loop in classical electromagnetism. It was derived by James Clerk Maxwell, not Ampère, and published in his 1861 work "On Physical Lines of Force"[2]. The modern version of the law, also known as the Ampère-Maxwell law, was created in 1865 after he added the displacement current term to the equation in order to generalise it to apply to time-varying currents. When Hans Christian rsted of Denmark noted that a compass needle near to a wire carrying current moved so that the needle was perpendicular to the wire in 1820, he realised that an electric current generates a magnetic field around it.

The current-carrying wire is encircled by magnetic field lines.

The plane of the magnetic field lines is parallel to the wire.

The magnetic field's direction changes if the current's flow is reversed.

The current's size has a direct correlation with the field's strength.

Any given point's field strength is inversely proportional to how far away it is from the wire.
