What happens when a permanent magnet is wound with a copper wire

Click For Summary
SUMMARY

Winding a permanent magnet with copper wire to create an inductor and connecting it to a voltage source influences the magnetic flux of the magnet. The effect on the magnet's strength depends on the direction of the current flow, which can either enhance or diminish the magnetism. Key factors include the magnetic hardness of the material, its hysteresis curve, and the strength of the current applied. A strong permanent magnet with weak current will experience minimal changes in its magnetic properties.

PREREQUISITES
  • Understanding of electromagnetic induction principles
  • Knowledge of magnetic materials and their properties
  • Familiarity with hysteresis curves in magnetism
  • Basic electrical circuit concepts, including voltage and current
NEXT STEPS
  • Research the effects of current direction on magnetic fields
  • Study the hysteresis curve of various magnetic materials
  • Explore the principles of electromagnetic induction in detail
  • Investigate the relationship between current strength and magnetic field intensity
USEFUL FOR

Physicists, electrical engineers, and anyone interested in the principles of electromagnetism and the behavior of magnetic materials in electrical circuits.

what happens when a permanent magnet is wound with a copper wire (inductor) and the inductor is connected to some volatge? Will the magnetic flux of the permanent magnet increase (i.e., make the permanent magnet more strong)?

Depends on which way the current is flowing. It can add or subtract. I don't know what the effect is on permanent magnets thought. It might destroy their natural magnetism.

It will increase or decrease, as was said, but by how much depends on the magnetic hardness of the material, its hysteresis curve, and the current. If the material is very hard, and the current is weak, the change will be very small.
