The magnitude of a vector can be found by taking the square root of each of the vector components squared. For example, if you had the vector 3i+4j, to find the magnitude, you take
sqrt ( 3²+4² )
To get:
sqrt ( 9+16 )
sqrt ( 25 )
= 5
Works the same in 3D or more, just put all the vector components in.

What does it mean to find the magnitude of a vector?
The magnitude of a vector is a geometrical value for hypotenuse.. The magnitude is found by taking the square root of the i and j components.
How do you find the magnitude and the direction of a vector?
Use trigonometry.

How do you find speed given a vector?
Given a vector, speed is the magnitude of the velocity vector, |v|. Consider vector V= IVx + JVy + KVz the magnitude is |V| = ( Vx2 + Vy2 + Vz2)1/2
