Document Summary
The french physicist andre marie ampere noiced that when one wire carrying an electrical current is brought near a second wire also carrying a current, the two wires experience forces. He states that the force is proporional to the product of the two currents and depends on the relaive posiions of the wires1. A moving charge in one wire must exert a force on a moving charge in the other wire. The force between the two wires is the sum of the individual forces between the moving charges. That force between the charged paricles due to their moion is called magneic force. To understand the magneic ield generated by the connecing rods, we need to verify the relaionship associated with the force between the two current carrying bars and the current in the wires. A current balance consists of two regular conducing bars arranged with one bar directly above the other2.
