Which of the loops would feel a magnetic force directed to the right?

Click For Summary
SUMMARY

The discussion centers on determining which rectangular wire loops experience a magnetic force directed to the right when placed in a uniform magnetic field that is out of the page. The right-hand rule was initially applied incorrectly, leading to confusion about the correct answer. The correct understanding emphasizes that the induced force opposes the change in magnetic flux through the loops, which is crucial for identifying the loops that would feel the magnetic force.

PREREQUISITES
  • Understanding of electromagnetic induction principles
  • Familiarity with the right-hand rule for magnetic forces
  • Knowledge of magnetic flux and its changes
  • Basic concepts of rectangular wire loops in magnetic fields
NEXT STEPS
  • Study Faraday's Law of Electromagnetic Induction
  • Learn about Lenz's Law and its application in magnetic fields
  • Explore the right-hand rule in various electromagnetic scenarios
  • Investigate the effects of different loop orientations in magnetic fields
USEFUL FOR

Physics students, educators, and anyone interested in understanding the principles of electromagnetism and the behavior of wire loops in magnetic fields.

Problem:

The figure shows a region of uniform magnetic field out of the page. Outside the region, the magnetic field is zero. Some rectangular wire loops move as indicated. Which of the loops would feel a magnetic force directed to the right?

Attempted Solution:

By right hand rule none of these had a magnetic force to the right.

NOPE. Not right. Not sure why its not right either.

Possible Solution Choices:

a) 1
b) 2
c) 3
d) 4
e) 1 and 2
f) 2 and 4
g) 3 and 4
h) none of them
