The frequency of the coil was set at 260Hz for this particular experiment. I didn't have a good way of quantifying the frequency of oscillations, but I would estimate it increased by half when I increased the voltage (from 500Hz to 750Hz would be my best guess). The voltage was increased from...
In my setup, it was the frequency of the oscillations that appeared to have increased. cpsinkule's logic is beginning to make sense as to why I'm seeing the increase in frequency, but I'm clearly no electrophysicist. I'm also starting to look at it from the opposite standpoint: that of a...
What would be the important characteristics to consider when looking at the frequency of oscillation? I don't think it's worth exploring a single setup if it will all change with the next, but from a high level is it at all fair to say that the stronger the magnetic field, the faster the...
Thanks for the analogy, it does help to understand from a high level why I'm seeing this, but I'd like to understand more detail (links to further reading would be excellent if you don't care to type it all out). Is there a formula for the real frequency based on magnetic field strength, magnet...
I set up an experiment where I drove a solenoid with an H-bridge circuit at one voltage, and then I repeated the experiment with a higher voltage. There was a magnet positioned above the solenoid such that it was free to oscillate side to side (see picture). My observation was this: with the...
