How do I make a coil cover half of a circle
How do I make a coil or a series of coil constantly move electricity as the magnet passes it in half of a circle/armature.
Do I simply make an oval shaped coil that covers the area I needed cover, or do I make a series of coil?
Think of it like a motor but instead, the coils are only on half of the armature.
OK, that's clear.
Here is a very quick sketch of how such a motor works.
The first bit shows the field of a helical coil is very similar to that of a bar magnet.
It has a North and a South pole, just like the bar magnet.
So the trick is to arrange as many small helices around you half circle as possible connected so that the present alternate North and South poles.
Such motors will 'stick' in one position and need to started by some other means.
