I would appreciate if anyone can advise as to how to make magnets. I have an electronic engineering background, but have never done this before. I want to make tiny magnets, say size of 4mm x 4mm or 6mm x6mm, of the power of 4000 to 5000 Gauss (higher the better)..
What material should I use ? What coating should I do on that material for corrosion protection ? What would be the thickness of the coating ? Should I do coating before / after magnetizing ? What would be the coil / dc power setup ? How do I measure the strength afterwards ?
Any advise would be great.
