I have question too. Is it possile with your software or formula to
determin if there is an homogenous magnetic field left if i elevate the
distance between to helmholtz coils. And if there is a field left how
big it is an how strong the magnetic fiels is?
The coils i use are 14 cm diameter helmholtz coils operated a max. 1,6 A
an 65 V. They have each 755 turns. The normal distance is 7 cm between
them. But at the experment i need a microscope an only can use them in a
distance of 12 cm.
Could you tell me if there is a homogenic magnetic field left an how
strong, big it is?
I don't have a clue how to calculate something like that because i'm not
physicist, i'm a chemist.
Perhaps you can give me a hint.
many thanks from germany
