The discussion revolves around the calculation of magnetic flux, specifically questioning the use of sine versus cosine in the formula. The original poster expresses confusion regarding the angle used in the magnetic flux equation, which is typically represented as NBA cos θ.
Participants are actively engaging with the problem, questioning the definitions and relationships of angles in the context of magnetic flux. Some guidance has been offered regarding the geometric relationships, and there appears to be a productive exploration of the topic.
There is an emphasis on understanding the angle between the normal of the surface area and the magnetic field lines, as well as the angle depicted in the provided diagram. The discussion reflects a need for clarity on these definitions and their implications in the formula.
I did know what the variables represent, the angle is between the normal of the area of the surface and magnetic field lines. But i still didnt get the reason.gneill said:
Okay, the angle in the given diagram does not subtend the area normal and the magnetic field direction. How does this given angle relate to the angle used in the definition? (It may help to use a little triangle geometry)watthappening said:
It's doesnt? oh well, I didnt know thatgneill said:
The required area normal is perpendicular to the area of the coil "face", that is, it's perpendicular to the plane of the coil. The angle shown in the diagram subtends the magnetic field and the plane of the coil itself.watthappening said:
is this correct?gneill said:
alright thanks for the help, mategneill said:
