QWORK Demonstration Induction Coil with Primary Coil, Secondary Coil and Cylindrical Magnet for Physics Teaching

Well-made, teacher and lab quality.

It's made well but there are no instructions or suggested use. I used it to create a magnetetic field for a class.

The coil I got is lightly damaged. The red tube is to protect the coil. It's shipped alone in a box - just sitting. I tested it, and the coil itself is fine. However, the specs for this are very demanding. Like more than 10w demanding. I didn't expect that for this price. It also seems hand assembled. I found it to be fairly well built. Transfer is great between coils. It has basically one use, which will be wireless charging power. This coil is no good for anything but science shows. If you want to play with it right, buy a couple of 6v batteries (the big ones) and hook them up. Bring resistors just in case.

Great Science Project

No instructions included so somewhat useless for us common folk trying to teach young people.

Better then trying to build one, Good quality !

Simple but useful to show kids electromagnetic effect and how transformers work.

The quality of the product seems good, but there is zero documentation with this. Even a website link to recommended videos would be helpful. I haven't had much success finding documentation/videos that use these specific items on line to know how much current I can put through them (Some other reviewers did post recommendations).
