Hi all physics teachers

I am looking for inductors in the range mH for usage with banana plugs for basic electronics physics labs (like resonance in RLC-circuits etc).

I know I can build my own very simple, but if you know a place where I can buy those pre-made I would be very helpful :)

I've used the Taiyo Yuden LHL08 inductors in many circuits, and it looks like they are available via Digikey. Does that work for you?

where you can just insert banana plug chords

Right now I have inductors which i place in these

One option would be to use a M/F banana plug and just use the built-in screw terminals to connect the leads of the inductor to the two parallel banana plugs. This is an example of what I'm talking about, although this particular one at Digikey is a bit pricey at $17. You can probably find less expensive ones...

The 200-turn coil is only $55.

Pasco is not known for their products being inexpensive. If it's institutional money I learned to not bat an eye. It's all "funny money".
