Magnitude of a Vector
Magnitude of a vector is the length of its directed line segment from the initial point to the terminal point. So, the magnitude of a vector is a positive number which is the measure of the line segment representing that vector. Magnitude of a vector is also known as the modulus or the absolute value of the vector.

Direction of a Vector
Direction of a vector is the
direction of the directed line segment representing that vector. Direction of a
vector is measured as the angle made by the vector with positive (i.e
anticlockwise) direction of X-axis.

Therefore, for the
direction of a vector, we find the tangent of the angle (θ) made by the given
vector with the X-axis in positive (anticlockwise) direction.
