The cross product will always be another vector that is perpendicular to both of the original vectors. The direction of the cross product is found using the right hand rule, while the magnitude of the cross product is given by:

## How to calculate the direction of a cross product?

In this rule, we can stretch our right hand in a way that the index finger of the right hand in the direction of the first vector and the middle finger is in the direction of the second vector. Then, the thumb of the right hand indicates the direction or unit vector n.

## Remember that vectors always have a magnitude and a direction. How do we find the direction?

For that, we need the right hand rule. To use the right hand rule, you first have to hold up your right hand. Make sure it?s not your left, or it won?t work!
