How much wider can I coil be to the width of a magnet?
For some reason, i suspect that a coil can be quite wide as long as there is
sufficent flux to saturate entire coil? Or is it somehow related to some designs where
the end turn is out of play but part of the design?
I am thinking maybe 2x the width of the coil?
errrr....that was confusing lol
okies, I am thinking that the coil may be as much as 2x as wide as the magnet used?
I come to this conclusion because I made a DIY magnet line viewer by cutting up steel wooll and
putting it into baby oil in a clear plastic bottle. Than I shake the bottle and lay over top of a magnet and
the magnetism grabs the steel wool bits in patterns. This way, I can see how far out the field lines travel.
I also am hoping that with this I can discover if i am having intermagnet flux loss from magnets being to close to each other.
But, basically, it appears to me that the field lines are as much as 100 percent the width of the magnet.
I can post pics if it helps.
