force on a moving charge in magnetic field

Need help in understanding the direction of magnetic force in the magnetic field!Totally confused by directions.

Why is it that magnetic force is perpendicular to the direction of magnetic field and velocity of charged particle. Why is it(force) not in the same direction as the magnetuc field

A magnetic field exerts a force on a moving charge. Given a magnetic field, $\vec{B}$, and a charge, $q$, moving with velocity, $\vec{v}$, the magnetic force, $\vec{F}$, on the charge is:$$\vec{F}= q(\vec{v} \times \vec{B})$$
The magnetic force is perpendicular to the direction of magnetic field because $\vec{v}$ and $\vec{B}$ are in cross product. Give this a read.
