Science Challenge: Prove these magnets won't move

Click For Summary
SUMMARY

The discussion centers on a science challenge involving an electromagnet and two permanent magnets, referred to as magnet A and magnet B. When the electromagnet is activated, magnet A, positioned north up, will rise while magnet B, positioned south down, will fall due to magnetic repulsion and attraction principles. The scenario also describes the behavior of the magnets when the paddle is flipped 180 degrees, demonstrating the concept of a "magnetic circuit" where the magnetic field lines interact. This experiment illustrates fundamental magnetic principles effectively.

PREREQUISITES
  • Understanding of electromagnetism and magnetic fields
  • Familiarity with the concepts of magnetic repulsion and attraction
  • Basic knowledge of experimental physics
  • Experience with scientific reasoning and hypothesis testing
NEXT STEPS
  • Research the principles of electromagnetism and their applications
  • Explore the concept of magnetic circuits in engineering
  • Learn about the behavior of magnets in various orientations
  • Investigate experimental setups for demonstrating magnetic forces
USEFUL FOR

This discussion is beneficial for physics students, educators, and hobbyists interested in electromagnetism, as well as engineers looking to understand magnetic circuits and their practical applications.

1) An electromagnet with north up
2) A paddle
3) A permanent magnet (magnet A) positioned north down on top of the left side of the paddle
4) A permanent magnet (magnet B) positioned south down on underneath of the right side of the paddle

Reasoning) If the electromagnet is turned on from the position seen in the video - http://www.youtube.com/watch?v=YHHab4c4hsk", magnet A will rise and magnet B will fall due to the laws of magnetic repulsion and attraction. When the paddle turns over 180 degrees, magnet A will be where magnet B was and magnet B will be where magnet A was.

Additional information) The magnetic field lines of the two magnets feed into each other, creating what is called, in some engineering circles, a "magnetic circuit".
