How will the inductance of the coil change when the frequency of the alternating current decreases by 4 times?

In this task, the inductance of the coil will not change. The inductive resistance of the coil will change 4 times, since the resistance is XL = 2 * n * f * L. Where F is the frequency of the alternating current passing through the coil. Where L is the inductance of the coil. Where n = 3.14 is constant. It can be seen from the formula that if you change the frequency of the alternating current by 4 times, then the resistance will change by 4 times. The inductance of the coil, when the frequency changes by 4 times, practically remains unchanged and does not depend on the frequency.
