Question on induced emf in a loop

Click For Summary
SUMMARY

The discussion centers on calculating the induced electromotive force (emf) in a square loop of wire with sides measuring 20 cm, subjected to a magnetic field of 0.750 T that is decreasing at a rate of -0.0350 T/s. The induced emf calculated is 1.40 x 10^-4 Volts, which results from the changing magnetic flux through the loop. The key takeaway is the importance of providing complete problem details to avoid confusion in physics problems.

PREREQUISITES
  • Understanding of Faraday's Law of Electromagnetic Induction
  • Knowledge of magnetic flux and its calculation
  • Familiarity with the concept of induced emf
  • Basic geometry of a square loop and its dimensions
NEXT STEPS

Hey, I'm in a high school AP class and am stuck! Can anyone help me with this problem concerning induced emf? I would surely appreciate it.

There is a loop of wire, shaped like a square. Each side is 20 cm long.
There is a magnetic field directed into the page.

What would be the way of finding out what the induced emf in the loop. The back of the book says that the answer is 1.40 x 10^-4 Volts.

That magnetic field must produce a varying magnetic flux.So how about telling the whole story...?

Daniel.
 
Its ok, I found out how to do it. I forgot to mention that the Magnetic field has an initial magnitude of .750 T, and is decreasing at a rate of -.0350 T/S (there's your reason for changing magnetic flux) :approve:
 
Please,next time,write the text of the problem.That way,we'd avoid confusions or misunderstandings...

Daniel.
 
no problem.
