As expected

I'll order this to whine some feel landings on a homemade alternator I created the alternator from scratch I'm in a nursing home and they're all amazed how could I do it? Well I prayed a lot and I went to Amazon to buy my parts and they arrived on time,but now I've got to run under fill wires with no iron core. you didn't iron core stator I'm just wanting to fill coils with the wire and put them around extra strong magnets I bought from Amazon the square ones in n 52 rare earth magnets these things I like to never got apart believe me it's the strongest magnet I've ever had be careful if you buy these magnet because they're very dangerous they are n52 rare earth magnets they're not for children or anyone under 21 years old, thank you Amazon for a great product

This is perfect for wire wrapping jewelry. Would buy again.

Fairly durable for its thickness and price, great for electromagnetics.

Was fine

Hardly a single kink in the entire roll, and those were minor. See attached image. The tube's diameter is 2 inches. Nearly the whole 1lb of wire was used to make this coil. I have taps looped ever 10 turns down the entire length. Will purchase again. Fantastic for crystal radios as well.

Using it for a RF balum
