Homework Help Overview

The discussion revolves around a problem related to magnetic flux involving a conductor shaped into a square and positioned in a magnetic field. The original poster attempts to calculate the magnetic flux using a specific equation but finds their answer to be incorrect.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the correct angle to use in the magnetic flux equation, with some suggesting that the angle should be measured with respect to the normal of the plane rather than the horizontal. There are inquiries about how to determine this angle accurately.

Discussion Status

Participants are actively engaging in clarifying the correct approach to finding the angle needed for the magnetic flux calculation. Guidance has been offered regarding the importance of the angle between the magnetic field and the area vector.

Contextual Notes

The original poster's calculation appears to be based on an incorrect assumption about the angle, which is currently under discussion. There is an emphasis on drawing diagrams to aid in visualizing the problem setup.

I have a question dealing with magnetic flux that I cannot seem to get. Please help

Question= A 2m conductor is formed into a square and placed in the xy plane. a magnetic field is oriented 30 degrees above the horizontal with a strength of 6T. What is the magnetic flux through the conductor?
I would solve this by using the equation: Flux = BAcos(theta) = (6T)(2^2)cos30 = 20.8
however this answer is incorrect. can anyone tell me what I am doing wrong
thanks!

I think you want the angle the field makes with the normal to the plane of the square - not 30 degrees.
 
ok, can you help me find the angle needed for the equation.
 
I would draw a diagram. Draw the plane as a horizontal line, then draw in the normal. Next draw in a line representing the magnetic field, lable the angle between the magnetic field and the plane. You want the angle between the magnetic field and the normal.

Hope this helps :smile:
 
Theta would be the angle between the Field and the Area Vector.

Try using your hands :-)
