Hi, hopefully someone here can help me! I'm interested in Halbach Arrays and specifically I want to make a circular array in which the field is amplified away from the array (as in above or below it), not to its inner diameter (or exterior circumference). Is this possible? On the web Ive seen images of wedge/arc shaped magnets making circular arrays but the fields seem to be within the same "plane" as the magnets (inner circle and outer circumference). The traditional straight "fridge magnet" 5 cube-magnet Halbach array does what I want but I need it physically in a circle.. what happens if you make the line say 15 cubes long and make it loop around on itself?
