Answer:

The discovery that one current-carrying wire exerts a force on a second current-carrying wire was made by <u>Ampere</u>

Explanation:

Two current carrying wires exert force on each other. This was discovered by Ampere. It is also known as Ampere's force law.

A current carrying wire produces magnetic field around it. Another current carrying wire kept nearby experiences magnetic force by the first one.

The force is given by:

$F= \frac{\mu _o}{2\pi} \frac{I_1I_2}{r}l$

where I₁ and I₂ are the currents in the two wires and r is the distance between them.

The force may be attractive or repulsive depending upon the direction of current flowing in the two wires.
