Help ~ Calculate the maximum noise voltage

Click For Summary
SUMMARY

The discussion focuses on calculating the maximum noise voltage induced in a circuit formed by two conductors, each 10 cm long and spaced 1 cm apart, in a 10-gauss magnetic field at 60 Hz. The calculated noise voltage is 377 microvolts (uV). Participants emphasize the need to apply the appropriate equations from "Electromagnetic Compatibility Engineering," specifically those related to induced voltage from changing magnetic fields.

PREREQUISITES
  • Understanding of electromagnetic fields and their effects on circuits
  • Familiarity with induced voltage calculations
  • Knowledge of the principles outlined in "Electromagnetic Compatibility Engineering"
  • Basic circuit theory, including conductor spacing and length
NEXT STEPS
  • Study the equations for calculating induced voltage in circuits from changing magnetic fields
  • Review Chapter 2 of "Electromagnetic Compatibility Engineering" for detailed methodologies
  • Explore practical applications of noise voltage calculations in circuit design
  • Investigate the impact of magnetic field strength and frequency on induced voltage
USEFUL FOR

Electrical engineers, students in electromagnetic theory, and professionals involved in circuit design and electromagnetic compatibility assessments will benefit from this discussion.

Help!~ Calculate the maximum noise voltage

Homework Statement


Two conductors, each 10-cm long and space 1-cm apart, form a circuit.
This circuit is located where there is a 10-gauss magnetic field at 60 Hz.
What is the maximum noise voltage coupled into the circuit from the
magnetic field?

Homework Equations


From this book--Electromagnetic compatibility engineering- Chapter 2

The Attempt at a Solution


377uV

Does anyone could teach me how to calculate it?

Thank you!

The link does not appear to be translating...

In any case, what is the equation that you use to calculate the induced voltage around a wire loop from a changing magnetic field? That's what you should use here...
