Students have asked these similar questions
Physics students, wanted to investigate the forces of attraction (F) between two parallel conductors carrying currents li and l2
(also known as Ampere's Law)
The students noticed that as the length of the parallel
conductors (/) was increased the force of attraction between
the conductors (F) also increased. The data collected is in the
|L= SA
