Unformatted text preview: magnetic contacts with one pointing along + z and one along
described by [ 1 ] =
where and i

= are real numbers with say, 0 i
z . The other two are identical contacts but ˆ
one points along + n and one along n where n = z cos + x sin .
a. Show that 1 and 2 can be written in the form i( aI + b respectively and obtain a and b.
b. Show that for the other two contacts we can write
