Force Between Two Parallel Currents - The ampere

The video tutorial explores the interaction between current-carrying wires, explaining how they attract or repel each other based on current direction. It delves into Ampere's study of magnetic fields and the forces between conductors, illustrating the calculations involved. The tutorial defines the ampere and coulomb, linking them to current and force. It also introduces Roget's spiral, a device demonstrating the attraction of parallel currents, enhancing understanding of magnetic effects.
