How many times will the interaction force of two parallel currents change when the current strength in each of them doubles?
To find the change in the force of interaction of the two indicated parallel conductors, we use the ratio: k = Fк / Fн = (k * Iк1 * Iк2 * l / r) = (k * In1 * In2 * l / r) = Iк1 * Iк2 / (In1 * In2 ).
Variables ratio: Iк1 (final current in the first conductor) = In1 (initial current in the first conductor); Ik2 (final current in the second conductor) = In1 (initial current in the second conductor).
Calculation: k = Ik1 * Ik2 / (In1 * In2) = 2In1 * 2In2 / (In1 * In2) = 4 p.
Answer: The strength of the interaction of the two indicated parallel conductors will increase 4 times.
