1MeV=1.61013J=1.61013m2kgs2

c=2.998108ms

MeVC=0.5341021mkgs

pe=14MeVc=7.471021mkgs


B=peqeR

1T=kgCs, qe=1.61019C, 1T=104G

B(T)=4.67102R(m)

1800=κ+900+β

1800=γ+900+β

κ=γ

R=acos(β)=acos(900κ)=asin(κ)

d=R(1cos(κ))=a(1cos(κ))sin(κ)

B(T)=4.67102sin(κ)a(m)

If κ=20 then sin(κ)=0.0348995 and our B-field becomes:

B(T)=0.163102a(m)

a0.12m for the coils under consideration. Hence, B-field is:

B=0.01358T=135.8G
