Why are eddy currents circular?

Click For Summary
SUMMARY

Eddy currents are primarily circular due to the induced electric field lines, which are influenced by the homogeneity of the magnetic field. While they tend to exhibit circular patterns, this is not universally true as their shape can vary based on external magnetic influences. The right-hand grip rule effectively demonstrates the relationship between the magnetic field and the direction of the induced currents.

PREREQUISITES
  • Understanding of electromagnetic fields
  • Familiarity with the right-hand grip rule
  • Basic knowledge of electric fields and currents
  • Concept of magnetic field homogeneity
NEXT STEPS
  • Research the principles of electromagnetic induction
  • Study the right-hand grip rule in detail
  • Explore the effects of magnetic field homogeneity on eddy currents
  • Investigate applications of eddy currents in real-world scenarios
USEFUL FOR

Students of physics, electrical engineers, and anyone interested in the principles of electromagnetism and their applications in technology.

The induced electric field lines are circular as shown in the figure.

Eddy currents are not always circular. They are susceptible to the magnetic field homogeneity. They are somewhat circular due to the electromagnetic field
which can be easily demonstrated with the right hand grip rule.
