SUMMARY

The discussion centers on the behavior of induced currents in a wire loop as it accelerates through a homogeneous magnetic field. The consensus is that the induced currents rank as I4 > I2 > I1 = I3 = I5 = 0, due to the changing magnetic flux only occurring at the edges of the field region. As the loop accelerates, the rate of change of flux increases, leading to stronger induced currents. The confusion arises from the assumption that regions of constant magnetic field would still induce current, which is incorrect.

PREREQUISITES
  • Understanding of Faraday's Law of Electromagnetic Induction
  • Knowledge of magnetic flux and its calculation
  • Familiarity with the concept of induced current
  • Basic principles of motion in magnetic fields
NEXT STEPS
  • Study Faraday's Law of Electromagnetic Induction in detail
  • Learn about the relationship between magnetic flux and induced current
  • Explore the effects of loop acceleration on induced electromotive force (EMF)
  • Investigate practical applications of induced currents in electrical engineering
USEFUL FOR

Physics students, electrical engineers, and educators seeking to deepen their understanding of electromagnetic induction and its applications in real-world scenarios.

A wire loop accelerates from position 1 to position 5. It enters an area of a homogenous non changing magnetic field B. Rank the induced currents in the loop starting from the biggest. in solutions it says I4>I2>I1=I3=I5=0 but i dont understand why

At the edge of the field region the flux through the loop will start changing. The faster the loop is moving (later in the acceleration) , the faster the rate of change of flux.

shouldnt it then be I5>I4>I3>I2>I1
 
The picture appears to be in Polish which is a problem for me........
I assume the places where I is zero are regions of constant field (no edges intersected by loop).

its croatian, but i translated the text i just put this for the drawing in case it is not clear from the text
what do you mean that edges arent intersected by loop
 
Croation.
The loop moves in a region of constant field then ##\frac {d \phi} {dt}=0##
