After laying low for awhile, cross products have suddenly became very important in our current independent unit on Magnetism. For those who may have forgotten how to find a cross product, here are some reminders.
1. Cross products are needed when the multiplication of vectors is involved in the problem
2. To find cross product of a x b [where a is (ax,ay,az) and b is (bx,by,bz)]
3. The cross product is then written:
a x b = (cx,cy,cz)
