Faraday disk/ how is the magnetic flux changing?

Click For Summary
SUMMARY

The discussion centers on the principles of electromagnetic induction, specifically regarding the Faraday disk. The user questions how current is induced when the magnetic field ("B") remains constant while the disk is spinning. It is established that a charge moving through a magnetic field experiences a force, which is crucial for understanding how magnetic flux changes and induces current. The conversation emphasizes the importance of the relative motion between the magnetic field and the conductive material in generating induced current.

PREREQUISITES
  • Understanding of Faraday's Law of Electromagnetic Induction

i can not seem to figure out how is the magnetic flux is changing and thus the current is induced , "A "is constant (same disk is spinning ) and "B" is constant and does not change , so how is the current induced ?
and more specifically how is the change of magnetic flux is happening ?
thanks for help .

Who is claiming that the magnetic field must change?
What happens to a charge moving through a magnetic field?
