Magnetic Field B Flux Through a Surface Explained

Click For Summary

Homework Help Overview

The discussion revolves around the concept of magnetic flux through a surface, specifically addressing the definition and implications when the magnetic field is not perpendicular to the surface. The context is within a level 2 physics course.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to define magnetic flux and considers the effect of the angle between the magnetic field and the surface. Some participants question the completeness of this definition, particularly regarding non-planar surfaces and varying magnetic fields.

Discussion Status

The discussion is ongoing with participants providing feedback on the original poster's definition. While some affirm the correctness of the explanation, others suggest exploring additional complexities related to the problem.

Contextual Notes

The assignment specifies the need to include cases where the magnetic field is not perpendicular, and it is noted that this is for a level 2 course, which may imply certain constraints on the depth of explanation expected.

I have been asked to explain what is meant by 'the flux of a magnetic field B through a surface' and to include the case where the field is NOT perpendicular to the plane of the surface.

This seems quite simple but i just wanted to check my definition with you guys

I have;

The flux of a magnetic field B through a surface is the the strength of the magnetic field over a given area A and is given by the equation magnetic flux=A*B

Where the field is NOT perpendicluar to the plane it is given by the inclined angle to the perpendicular and given by the equation A*Bcos(theta)

Is that pretty much it?
Hope so :)

That's OK, you are not saying anything incorrect. I am not sure though how complete your answer must be. For example, what happens when the surface is not a plane or when the magnetic field changes magnitude and/or direction from one point of the surface to the next. To get a better picture see the wikipedia article

The quation just says; Expalin what is meant by"'the flux of a magnetic field B through a surface' Include the case where the magnetic field is NOT perpendicular to the plane of the surface.
Its a level 2 course
 
You are fine with what you have then.
