Calculating/estimating Eddy currents due to B-field

Click For Summary
SUMMARY

This discussion focuses on calculating the magnitude of eddy currents generated in ultra high-speed rotating discs, specifically those made of aluminum alloy or non-magnetic stainless steel, when subjected to the electromagnetic field of a solenoid lens. The user seeks guidance on this topic after a long hiatus from related calculations. Reference is made to Smithe's "Static and Dynamic Electricity" as a potential resource for understanding the principles involved in eddy current generation in such scenarios.

PREREQUISITES
  • Understanding of electromagnetic fields and their effects on conductive materials
  • Familiarity with eddy currents and their generation in conductive materials
  • Knowledge of the properties of aluminum alloy and non-magnetic stainless steel
  • Basic principles of solenoid lenses and their applications in electron beam focusing
NEXT STEPS
  • Research the principles of eddy current generation in conductive materials
  • Study Smithe's "Static and Dynamic Electricity" for detailed calculations
  • Explore the effects of high rotational speeds on electromagnetic interactions
  • Investigate simulation tools for modeling electromagnetic fields and eddy currents
USEFUL FOR

Engineers, physicists, and researchers involved in electromagnetic applications, particularly those working with high-speed rotating machinery and electron beam technologies.

Its been 15+ years since I have done any calcs like this and am very rusty, so even just a pointer in the right direction would be really appreciated...

I need to calculate/estimate the magnitude/value (IF any!) of eddy currents that would/could be generated in an ultra high speed rotating disc (>35,000 rpm) made of aluminium alloy or non-mag stainless steel, when placed/located such that it intercepts at/near the 'focus' of a electromagnetic solenoid lens (used to focus an electron beam).

Anyone?

If I'm not mistaken, Smithe's "Static and Dynamic Electricity" addresses that topic
