Magnetic Flux through a Loop Calculation

Click For Summary
SUMMARY

The discussion focuses on calculating the magnetic flux through a loop with dimensions 22 cm and 27 cm, subjected to two magnetic fields of 1.2 T and 1.7 T. The formula used for magnetic flux is MF = AB cos θ, where A is the area and B is the magnetic field strength. The user initially attempted to calculate the flux by summing the contributions from both magnetic fields but overlooked the fact that the fields point in opposite directions, which affects the total flux calculation. Correctly accounting for the direction of the magnetic fields is essential for obtaining the accurate result.

PREREQUISITES
  • Understanding of magnetic flux and its calculation.
  • Familiarity with the formula MF = AB cos θ.
  • Knowledge of the concept of magnetic field direction.
  • Basic geometry for calculating the area of a rectangle.
NEXT STEPS
  • Review the concept of magnetic flux and its applications in electromagnetism.
  • Learn how to apply the right-hand rule to determine the direction of magnetic fields.
  • Study the effects of opposing magnetic fields on total flux calculations.
  • Explore advanced topics in electromagnetism, such as Faraday's Law of Induction.
USEFUL FOR

Students studying physics, particularly those focusing on electromagnetism, as well as educators looking for practical examples of magnetic flux calculations.

Homework Statement

What is the magnitude of magnetic flux through the loop? (a=22 cm, b=27 cm, B1=1.2 T, B2=1.7 T.)


Homework Equations


MF = AB cos theta


The Attempt at a Solution


MF = AB
So wouldn't I just do ((0.2m * 0.2m) * 1.2) + ((0.22m * 0.27m) * 1.7)
but that's not getting me the right answer...what am I doing wrong?

Remember that the fields point in opposite directions in the two regions...
 
oh yea thank you!
