The Electromagnetic Induction Apparatus with Magnet features a single turn of thick wire manually rotated around a sturdy magnet rod. This device explores the concept of a conductor intersecting magnetic flux at a fundamental level and also includes a "mystery" presented for instructional use.

The apparatus utilizes a metal conductor, mounted between two bearings, to rotate like a single blade of a paddle-wheel. A slim cylindrical permanent magnet is horizontally supported by sliding it through the bore of one bearing. The magnet's length is parallel to the conductor, with its tip positioned halfway along the conductor's length. By passing through a single turn, the magnetic field is cut which generates a minute voltage that can be easily detected with a highly sensitive meter.

soft and cottony.
Soft, cottony, do not dissolve immediately. I use these to soak my eyes with warm water and they hold well for the 4-5 times of soaking and putting on the eyelids ordered by my ophtamologist. They won't hold for more that 4-5 soaks though. They are also excellent for eye make-up removal.

These cotton balls are large
Because these are so large, you only need one. They’re more expensive, but because you only need one, they go a long way. They’re worth the he price, I think. The ones I’ve bought that are cheaper & much smaller, you usually have to use 3-4 balls. Try ‘em you’ll love them!

Decent but not my favorite
I wish I hadn’t ordered such a large box of these but I’ll make them work. The little sleeve is a nice idea but my fingers still slide out when I’m using one for toner or to remove makeup. And the edges sometimes scratch my face, only the middle “pillow” part is soft. Overall very “meh” lol
