Question

Deriving Ampère's Circuital Law from Ampère's Force Law?

Answer 1

Ampère formulated Ampère's force law, which describes the attractive or repulsive force between two current-carrying wires.) When the wire is a loop, the magnetic field causes a forcein one direction on one side of the loop, and in the opposite direction on the other side of the loop.

hope it clarifies ur doubt dear friend..

Answer 2

$\textbf {\huge{ \red {ANSWER }}}$

This leads through a plausibility argument to the existence of a magnetic field and the Lorentzforce law.
