In the center of the solenoid with a current I1 = 50 mA there is a round circuit through which a current I2 = 100 mA flows. The length of the solenoid is 50 cm, the number of turns N1 = 1000. The number of turns of the circuit N2 = 20, its radius R = 1 cm, the plane of the circuit turns is parallel to the axis of the solenoid. At what angle to the solenoid axis is the magnetic field induction directed at the center of the circuit? Find the value of this induction.
