Задача 30488.

Two circular turns with a radius of 4 cm each are located in parallel planes at a distance of 5 cm from each other. Currents I1 = I2 = 4 A flow through the turns. Find the magnetic field induction in the center of one of the turns. The problem is solved for the cases: I) currents in the turns flow in one direction; 2) currents flow in opposite directions (medium - air).

A detailed solution with a brief record of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have questions about the solution, write. I try to help.
