Two tram wires with a current of 700A each are located at a distance of 3m from each other. find the force of interaction between the wires for every 30 meters of length.
Initial data: I (current in tram wires) = 700 A = I1 = I2; d (distance at which the wires are located) = 3 m; Δl (considered section of the length of tram wires) = 30 m.
Constants: km (proportionality coefficient) = 2 * 10 ^ -7 N / A2.
The force of interaction between tram wires is determined by the formula: Fa = km * I1 * I2 * Δl / d = km * I ^ 2 * Δl / d.
Let’s calculate: Fa = 2 * 10 ^ -7 * 700 ^ 2 * 30/3 = 0.98 N.
Answer: The force of interaction between tram wires is 0.98 N.
