In the middle of a long solenoid is part of a conductor, the current in which A 4 and 2 cm length. The conductor is perpendicular to the axis of the solenoid. This conductor segment a force of 10 ^ -5 H. Determine the current in the solenoid coil with the proviso that 1 cm length of the solenoid coils 10 falls and the core no.
Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
