Two identical small coils are arranged so that their axes lie on the same straight line (figure). The distance between the coils l = 10 cm significantly exceeds their linear dimensions. The number of turns is N, the area of turns is S = 10 cm2. With what force do the coils interact when the same currents I = 0.1 A flow through their windings? What is the coefficient of mutual induction of the coils M?
