A certain substance is placed in a longitudinal magnetic field of a solenoid located between two Polaroids. The length of the tube wity substance is equal to `l = 30 cm`. Find the verdet constant if at a field strength `H = 56.5 kA//m`, the angle of rotation of polarization plane is equal to `varphi_(1) =+ 5^(@) 10`' for one direction of the field and to `varphi_(2) =- 3^(@) 20`,' for the opposite direction.
