Calculating Halbach Array force
Calculating Halbach Array force
(OP)
So I'm thinking of this shock absorber involving magnets, but to reduce the weight as much as possible, I thought about using a halbach array of magnets to be able to repel as strongly as possible with the least amount of weight.
The only problem is that I haven't got a clue as of how to calculate how strong a halbach array would repel something!
So, are any of you familiar with the concept?

spring --> r --> constant jerk
The degree of jerk would be unacceptable for most applications

A theoretcial equation for the magnetic flux density (B) inside a two pole Hallbach Array is (Flemming Buus Bendixen/Anette Norskov Shultz):
B=Br*log(Ro/Ri)
where Br is remanence of the magnet
Ro is outside radius and Ri is the inner radius of the magnet array.

I'm not sure if it would have any effect, but it would help if I could actually calculate how much [non-cylinder] halbach arrays repel!
So thanks for the suggestion Clyde, but it was a slight miss in the description there :p
