Need help with Dynamo rule applied to coil and magnet:

Click For Summary
SUMMARY

The discussion centers on the principles of electromagnetic induction as applied to a bar magnet moving within coils. It is established that moving a magnet inside coils can indeed induce a current, even if the motion is parallel to the magnetic field lines. The key factor is the change in magnetic flux through the coils, which occurs regardless of the angle of motion. Therefore, current will be induced as long as there is relative motion between the magnet and the coils.

PREREQUISITES
  • Understanding of electromagnetic induction principles
  • Familiarity with Faraday's Law of Induction
  • Basic knowledge of magnetic fields and flux
  • Experience with coil and magnet setups in physics experiments
NEXT STEPS
  • Study Faraday's Law of Induction in detail
  • Experiment with different orientations of magnets and coils to observe induced currents
  • Learn about Lenz's Law and its implications on induced current direction
  • Explore applications of electromagnetic induction in generators and transformers
USEFUL FOR

Physics students, educators, and hobbyists interested in understanding electromagnetic induction and its practical applications in electrical engineering.

Hi, (I posted this on TSR as well, but they're being a bit slow...)

Take the following setup:

If you move the bar magnet left and right (a few cm) inside the coils, so that the ends do not leave the coil, will it induce a current/emf? I presume it does so, as I have been taught.

But I don't see why it will induce a current, since the motion in not perpendicular to the field lines. I haven't drawn the field lines in, because that would be a bit hard to do in paint lol. But I hope you can see what I mean.

Like, to induce a current, the motion of the conductor would have to CUT across a magnetic field perpendicularly. At the moment, the coils are effectively moving parallel to the magnetic field, since the magnet is being pushed left and right.

So this is basically the same diagram as above:

In this case, no current would be induced..right?

I know I am wrong somewhere, and I think I know where it is, but Ill let some people explain before I tell.

Thanks!
