Driving a coil...Voltage drive..? Current drive..?
Hi Guys
As the title...I am now having a 10 turns coil, does it really matter that I drive it with sinusoidal voltage signal or a sinusoidal current signal? Will it affect the response of the coil? (like resonance frequency, Q factor...etc)
I am still doing the mutual inductance experiment..(thanks for u guys' help previously! especially Berkeman and Waht)...I am now having a identical coil as the transmitter to be a magnetic induction detector (properly shielded..) what I observed is that the Q factor of my detecing coil is extremely high~! the magnitude of the detected signal at resonance is like 30 times more than the other frequencies...is that a normal observation?
And also, I am now thinking using a PCB coil instead of hand made coil (to make sure all the coils are identical...)Does anyone has this kind of experience? (like the shielding of the PCB...etc)
Thanks you so much for you guys' time!
