Measuring Frequency of an EMF with Gaussmeter: An Inquiry

AI Thread Summary
To determine the frequency of the generated electromagnetic field from the coils excited with 15 V AC, it is noted that the frequency of the electromagnetic field (f_field) matches the frequency of the AC source (f_AC source). For example, if the AC source operates at 60 Hz, the electromagnetic field will also oscillate at 60 Hz. This relationship is based on the principle that the magnetic field direction changes in sync with the voltage alternation. Therefore, measuring the frequency of the AC source provides the frequency of the electromagnetic field. Understanding this relationship is essential for accurate EMF analysis.

Hello,
I got two series connected coils which I exited with 15 V AC. I got EMF between the space in the field and I measured it with gaussmeter saying 200 µT. I want to know the freqency of that generated electromagnetic field? Does anyone know how to do it? Is there any Equation for it?
Thanks,
Mit

Hi MIT. ##\quad## How about ##\ f_{\rm field} = f_{\rm AC\ source}\ ## ?
 
The frequency which the B field changes its direction is the same frequency which the Voltage alternates. If you had a 60hz Vac, the B field would follow also this frequency.

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
