Measure Magnetic Field Frequency - Handheld Meters

AI Thread Summary
To measure the frequency of a magnetic field, handheld meters typically only detect frequencies in the MHz range, which may not be suitable for lower frequencies like 1 Hz or 10 Hz. Users are questioning the effectiveness of these meters for oscillating magnetic fields and the expected frequency ranges. An alternative method suggested is using an oscilloscope or frequency counter with an inductor as a pickup probe to capture lower frequency magnetic fields. Understanding the limitations of available handheld meters is crucial for accurate measurements. Proper tools and techniques are essential for effectively measuring magnetic field frequencies.

Does anyone know how to measure the frequency of a magnetic field? They sell handheld meters but they only measure Mhz and higher

Frequency of what? An oscillating magnetic field? Which frequency range do you expect? 1 Hz, 10Hz, ..., 1MHz?

Do you have access to an oscilloscope or frequency counter? If so, you may be able to just use an inductor as a pickup probe for the magnetic field.
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
