   What is a cross product?

   • The cross product results in a vector, so it is sometimes called the vector product. These operations are both versions of vector multiplication, but they have very different properties and applications. Let’s explore some properties of the cross product. We prove only a few of them.

   What is a cross product A B?

   • The cross product ⇀ a × ⇀ b (vertical, in pink) changes as the angle between the vectors ⇀ a (blue) and ⇀ b (red) changes. The cross product (purple) is always perpendicular to both vectors, and has magnitude zero when the vectors are parallel and maximum magnitude ‖ ⇀ a‖‖ ⇀ b‖ when they are perpendicular. (Public Domain; LucasVB ).

   Can two vectors be multiplied using a cross product?

   • Two vectors can be multiplied using the "Cross Product" (also see Dot Product) The Cross Product a × b of two vectors is another vector that is at right angles to both: And it all happens in 3 dimensions! The magnitude (length) of the cross product equals the area of a parallelogram with vectors a and b for sides:

   How do you write a cross product between two vectors?

   • We write the cross product between two vectors as a → × b → (pronounced "a cross b"). Unlike the dot product, which returns a number, the result of a cross product is another vector. Let's say that a → × b → = c → . This new vector c → has a two special properties. First, it is perpendicular to both a → and b → .

   cx = aybz − azby. cy = azbx − axbz. cz = axby − aybx. Example: The cross product of a = (2,3,4) and b = (5,6,7) c x = a y b z − a z b y = 3×7 − 4×6 = −3. c y = a z b x − a x b z = 4×5 − 2×7 = 6. c z = a x b y − a y b x = 2×6 − 3×5 = −3. Answer: a × b = (−3,6,−3)

    The cross product of two parallel vectors is 0, and the magnitude of the cross product of two vectors is at its maximum when the two vectors are perpendicular. There are lots of other examples in physics, though. Electricity and magnetism relate to each other via the cross product as well.
