b.) Helmholtz coil are a pare of N-turn coils of radiusRsperated by exactly R. The e/m apperatus is designed so thattheelectron travels in the region directly between thecoils. Usingyour expression for above, what is the magneticfield directlybetween a pare of Helmholtz coils?
Inner radii of the coils used= 2.8cm
Outer radii of the coils used= 6.5 cm
Average value Radius R= 3.5 cm
N=130 turns
N = ( the number of turns in each coil), to determinthemagnetic field as a funtion of current.
