Few months ago, I tried enlisting members for a group magnet buy for shop/parts pickup use.
Needing diodes, INEXPENSIVE DIODES !, I odered from
ALLECTRONICS.COM including
maybe pickup magnets
MAG-143
10MM NEODYMIUM DISC MAGNET
and piezo sounders for muh van.
Magnets are AAA, small, stackable for strength, and strong. 2 stacked on a metal partition are finger difficult to pry off. I exercise with wrist grips for tool, bar, and paddle use.
Hafta check with McMaster Carr for a flexible rod.
