Orientation of Magnetic Field and Coil

Click For Summary
SUMMARY

The discussion focuses on the qualitative relationship between the induced electromotive force (e.m.f.) in a coil rotating perpendicularly to a magnetic field and several key factors: the position of the coil, magnetic flux density, coil area, and angular velocity. The participant initially sought clarification on which diagram best represented the scenario described in their A-Level specification, ultimately concluding that they had resolved their confusion independently. This highlights the importance of understanding the principles of electromagnetic induction as outlined by Faraday's Law.

PREREQUISITES
  • Understanding of Faraday's Law of Electromagnetic Induction
  • Knowledge of magnetic flux and its calculation
  • Familiarity with the concepts of angular velocity and its impact on e.m.f.
  • Basic principles of coil design and area calculation
NEXT STEPS
  • Study the mathematical formulation of Faraday's Law in detail
  • Explore the effects of varying magnetic flux density on induced e.m.f.
  • Investigate the relationship between coil area and induced voltage
  • Learn about practical applications of rotating coils in generators
USEFUL FOR

Students preparing for A-Level physics, educators teaching electromagnetic theory, and anyone interested in the practical applications of electromagnetic induction in engineering and technology.

Homework Statement



Not technically a homework problem, has arisen as a point on my A-Level specification and I'm a little unsure as to how they are seeing this situation.

"Relate qualitatively the instantaneous e.m.f. induced in a coil rotating at right angles to a magnetic field to the position of the coil, flux density, coil area and angular velocity;"

I have attached two diagrams and am not sure which one they are describing. I think it's most likely to be diagram A. Could someone confirm this for me please?
