Eddy Current Hazards: Magnetic Field & Human Body

Click For Summary
SUMMARY

The discussion centers on the hazards posed by a 10k Gauss magnetic field generated by an external electromagnet when it collapses through a standing human body. It raises concerns about the potential for harm from repetitive pulses and the necessary increase in Gauss to create a lethal shock hazard. The conversation also touches on the comparison of this magnetic field strength to that of medical MRI scans, emphasizing that while MRI safety precautions exist, eddy currents in human tissue are not typically a primary concern.

PREREQUISITES
  • Understanding of electromagnetism and magnetic field strength
  • Knowledge of eddy currents and their effects on biological tissues
  • Familiarity with safety protocols in medical imaging, particularly MRI
  • Basic principles of pulse duration and its impact on human physiology
NEXT STEPS
  • Research the effects of high Gauss magnetic fields on human health
  • Learn about the safety measures associated with MRI scans
  • Investigate the concept of eddy currents in conductive materials
  • Explore the relationship between pulse duration and electrical hazards
USEFUL FOR

This discussion is beneficial for medical professionals, safety engineers, and researchers in the fields of electromagnetism and biomedical engineering, particularly those focused on the effects of magnetic fields on human health.

Suppose a 10k Gauss 3in diameter sharp magnetic field is made & collapses completely thru a standing human human body somewere made by an external electromagnet.. The electromagnet is held horizontally and not vertically against body. Is this hazardous? Can it become hazardous after some duration with repetitive pulses? How many orders of magnitude greater would the Gauss need to be increased to become a lethal shock hazard from 1 pulse?

Thank you.

What's a "sharp" magnetic field? How does your field strength compare to a medical MRI scan?

There are important safety precautions in MRI scans (can you name a few?), but AFAIK, eddy currents in human flesh and bone are not one of them.
 
For this it can be a 10mS duration pulse.
