12. B2 rotates H through an angle of : 180
I was trying to paste the text, but it is too large.
But it said in passage that "B1 is always perpendicular to B2"
and "nucleus is antiparallel (becomes 180) with B1"
My reasoning is:
if B1 is perpendicular to B2, nucleus is antiparallel to B1,
then nucleus is perpendicular to B1(90)
But I must be wrong. Could someone please explain this one? I would really appreciate your help!! Thank you!
