The shape really doesn't matter. Whatever shape is best.
Could you explain a closed magnetic circuit to me?
To my understanding, a closed magnetic circuit would be where the magnets are in direct contact. I can only assume that an almost-closed magnetic circuit would be where the magnets are...
If I have a block of N52 and I want to make it's magnetic field as strong as possible, would a Halbach array give me this maximum or is there a different pole arrangement/array that would provide this? I'm thinking for the use in a motor, so the field doesn't have to be large. A close field...
Summary: For the same mass of copper wire, would more turns or greater thickness create a stronger magnetic field from a coil?
So I am attempting to make a brush less DC motor, and I am wondering whether the coils would create a greater magnetic force if there are more turns or if the wire is...
