Solution to task 453 from Chertov´s for extramural stud

453. In the middle part of the solenoid containing n = 8 turns / cm, there is a circular turn with a diameter of d = 4 cm. The plane of the turn is located at an angle φ = 60 ° to the solenoid axis. Determine the magnetic flux Ф, penetrating the turn, if a current I = 1 A. flows through the solenoid winding.
