Electromagnetic field question

AI Thread Summary
To find the magnetic field B inside a large field coil after measuring the induced emf on a test coil, one can use Faraday's law of electromagnetic induction. The induced emf in a coil is proportional to the rate of change of the magnetic flux through the coil. For an alternating current (AC) magnetic field, the equation for induced emf can be expressed as emf = -dΦ/dt, where Φ is the magnetic flux. Understanding the relationship between the induced emf and the magnetic field will help in calculating B. Further clarification on the specific equations and parameters involved may be necessary for a complete solution.

I'm presuming that they are talking about an AC B-field.

What is the equation for the EMF induced in a coil immersed in an AC magnetic field?
