Faraday effect in glass cell within solenoid

[ZedCar]

Homework Statement

Describe the Faraday effect as it might be observed in a glass cell contained within a
solenoid

Homework Equations

The Attempt at a Solution

When a glass cell is immersed in a strong magnetic field, the plane of vibration of light waves is rotated. When the solenoid receives the electrical current it sets up a magnetic field in the glass cell. The strength of the field varies in proportion to the amplitude of the signal current.
As the waves proceed through the glass cell the plane in which they vibrate is rotated by an amount that varies with the strength of the magnetic field and hence with the strength of the electrical current.

This phenomenon is known as the Faraday effect. When light passes through the glass cell and is observed by a viewer, the effect of the Faraday effect can be seen as a colour change in the light waves.
