Hi everybody,
I am new to electronics & am in need of some help, i want to test the magnetic field strength of some coils--metal detector coils in particular.
I have a PC based oscilliscope, voltmeter, function generator that i can use to gather some data.
My first question is:
Is there any difference between AC & DC magnetic field detection apparatus or is it basically all the same?
I need an easy to make electronic circuit that i can connect to my PC to collect some data.
I have found a Circuit that i have attached & was wondering if instead of using the needle type gauge if i can connect onto this to read from my PC based voltmeter. Or if in fact this circuit will do the job.
Or is there a simpler more effective way to do this.
Someone told me to use just a large coil of wire with a capacitor across the two wires but i am unsure what there talking about or how to set it up.
I don't know all the electronics talk so please take it easy with the replies
Thanks
