Unformatted text preview: magnetic contacts with one pointing along + z and one along described by [ 1 ] = where and i 20 0 ,[ 2 = are real numbers with say, 0 i 20 > ˆ z . The other two are identical contacts but ˆ ˆ ˆˆ 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 3 = and i ( aI + b cos 2 3 = z + b sin i ( aI b cos 2 z x ) b sin x ) respectively. z ) /2 and i( aI b z ) /2 12/3/09 2 c. For...
