SUMMARY

In induction cooking, the dominant effect at frequencies ranging from 30-50 KHz is the eddy current effect, while hysteresis plays a minimal role. This conclusion is based on the principles of induction heating, where eddy currents are generated in conductive materials, leading to efficient heating. The discussion emphasizes the importance of understanding these effects for those involved in designing induction cooktops.

PREREQUISITES
  • Understanding of induction heating principles
  • Familiarity with electromagnetic induction
  • Knowledge of material properties related to eddy currents
  • Basic concepts of hysteresis in magnetic materials
NEXT STEPS
  • Research the principles of induction heating in detail
  • Explore the role of eddy currents in different materials
  • Study the effects of frequency on induction heating efficiency
  • Investigate design considerations for induction cooktops
USEFUL FOR

Engineers, product designers, and researchers involved in the development of induction cooking technologies and those interested in the physics of heating methods.

What is the context of your question? Are you building an induction cooktop?
 
A sort of and i want to know about which effect is dominant at frequencies in range of 30-50 KHz.
 
Eddy currents. Hysteresis to a very little extent, if it really does. You would have got easily an answer if you had tried the wiki.

Is this for a schoolwork assignment?
