More on the toroid “cheat” hack

Remember Jim’s toroid hack that he posted here last week?  It was featured on hackaday, which was really cool to see.

Jim updated his post to his own blog to include some measurements of the effect of breaking the magnet to get the wire wrapped on to it.

He used a simple RL circuit to measure the inductance of the toroid. Very neat to see some values to compare the glued vs. unbroken magnets.

Thanks, Jim!
