when magnetic force can't accelerate a charged particle then why its called a force.

Here is your answer
The magnetic force (assuming you mean the force that a particle experiences when traveling through a magnetic field) does accelerate the particle. It does so in a direction perpendicular to the field and to the direction of the particle, the term in the force equation is the vector product between the velocity and the field. Because the acceleration is normal (which means perpendicular) to the velocity, the speed (which is the magnitude of the velocity) does not change, but the velocity most certainly does.
E.g., the charged particles from the sun are captured by Earth‘s magnetic field and then spiral along the field lines until the hit the atmosphere where they become the Northern or Southern Lights.
The magnetic field accelerates the charged particle by changing the DIRECTION of velocity. The magnetic field does NOT change the SPEED if the charged particle.
A vector quantity is comprised of both direction and magnitude. Velocity is a vector quantity. The magnitude of velocity is the speed.
The reason that the magnetic field doesn’t affect the speed is because the magnetic field applies a force perpendicular to the velocity. Therefore, the force can’t do work on the particle. So the particle can’t change its kinetic energy. so it can not change the speed.
