the magnitude of a vector is the length of the vector... thus you are not interested in the direction that the vector has...
thus it is scalar... an entity without direction... §

a vector must have 2 things in order to be considered a vector (direction & magnitude). since the direction of a vector has the magnitude of 1, we can multiply it with a fraction or whole number in order to give it the desired magnitude; hence the name scalar. see below for example 1. being direction and 2 being magnitude with this in mind, if I wanted to direct a blind person some where, first I would tell him the direction (left or right, up or down) then I would tell him the magnitude (take 2 steps, 2 feet, 2 yards etc. another example would be a blind person shooting a 3 pointer. First you tell him the direction on where to shoot (45 degrees, to the left, right etc). Then you tell him how much strength he needs to exert on the ball to send it to the basket. if you find this useful, hook me up with best answer

A vector has magnitude AND direction
A scalar has magnitude only.
Example
Vector v = 5 /_ 30° = 5 (cos 30° + i sin 30°)
magnitude 5
direction 30°

Magnitude is simply a number or a value and so, doesn't have a direction.therefore it is a scalar.
