How can Resistance be increased w/ rare earths?

[MrEvolve]

Im new to the magnetic inovation world myself. Im currently trying to find a way to increase resistance because pull to me means nothing really for what im working on. Im a machinist from Michigan I am experimenting w 2x 2" dia 2" 1/2 inch long neodyme boron & Ni rare earths. they have a pull of 259lbs each @ zero. And when held 1" apart they have a resistance of only 70lbs. any tipps would be helpful... Thank you

Increase resistance to what... sliding?
In that case you're looking for a way to make the surface rougher?
