Does Rolling a Magnetic Core on a Magnet Affect Its Properties?

Click For Summary
SUMMARY

Rolling a magnetic core on a magnet does not inherently increase its permeability or magnetic field strength. The discussion highlights the importance of the core's material composition, such as ferrite, powdered iron, or laminated steel, and its shape, including whether it is toroidal. The interaction between the core and the magnet is influenced by these factors, as well as the core's initial magnetization state. Understanding these variables is crucial for determining the effects on magnetic properties.

PREREQUISITES
  • Basic understanding of magnetism and magnetic fields
  • Knowledge of magnetic core materials (ferrite, powdered iron, laminated steel)
  • Familiarity with core shapes and configurations (e.g., toroidal cores)
  • Concept of permeability in magnetic materials
NEXT STEPS
  • Research the properties of different magnetic core materials
  • Study the effects of core shape on magnetic performance
  • Learn about the principles of magnetic permeability
  • Explore experimental methods for measuring magnetic field strength
USEFUL FOR

Physicists, electrical engineers, and materials scientists interested in magnetism and magnetic core applications.

Hi

Quick question related to magnetism

If I have a magnetic core and place that core onto a magnet, then roll the core on a flat surface ( whilst its still on the magnet), does that increase the permeability and magnetic field of that core ? If so, what is the theory behind that.

thank you in advance

Can you upload a sketch please (use the "Attach files" link below the Edit window).

Also, what shape magnetic core? Is it magnetized in some way? And what do you mean by "placing it on a magnet"?
 
What grade of material is the core made from?
Ferrite, powdered iron, or laminated steel?
Is it toroidal core?
