**Lorentz**Law says that for a charged particle moving with a velocity

**v**in a magnetic field

**B**then the force on it is given by $$ \mathbf{F} = q (\mathbf{v} \times \mathbf{B}) $$

Now, if I say that particle’s velocity and the magnetic field are aligned then according to

**Lorentz**Law there will be no force on it and hence no attraction.

If we have something that have a magnetic moment [itex] \mathbf{\mu}[/itex] then the torque produced by magnetic field on it is $$ \tau = \mathbf{\mu} \times \mathbf{B}$$

So, magnetic field seems to me to work only in rotational aspects and never causes any translational effect. I want to know if this is true.
