Answer:
 force is exerted on a charge carrying particle by a MAGNETIC FIELD only when the particle moves PERPENDICULAR the field lines. If a charged particle moves parallel to the magnetic field, the force exerted by the magnetic field on the charged particle is_ ZERO
Explanation:
This complementation exercise refers to the magnetic force that the formula has
     F = q v x B
where the bold letters indicate vents and the x the vector product. The module of this product is
     F = qv B sin θ
where θ  is the angle between the speed and direction of the magnetic field.
It can be seen that for the force to be different from zero, the angle must not be parallel θ  = 0
    sin 0 = 0
the maximum value is obtained for an angle of θ  = 90º
    sin 90 = 1
Using these concepts we see that the missing words are.
 force is exerted on a charge carrying particle by a MAGNETIC FIELD only when the particle moves PERPENDICULAR the field lines. If a charged particle moves parallel to the magnetic field, the force exerted by the magnetic field on the charged particle is_ ZERO_______
