Is Magnetic Force Conservative or non conservative in nature?

forcefield is conservative, if its rotor vanishes, in your case that would mean that:

rot(B) = 0.

if you look at Maxwell's equations, it holds that: rot(B) = µ_0*j + µ0*e0*dE/dt
(where µ0 ... magnetic constant, e0 ... vacuum permittivity, dE/dt ... in this case the PARTIAL derivative of your electrical field, j ... your current density).

So, I would say, no, the magnetic force field is in general not conservative

If a magnetic field is changing, then it generates an electric field according to Faraday's law of induction, and that magnetically generated electric field will run in closed paths and be non-conservative (unlike electric fields generated from static charges).
The magnetic field itself is neither conservative nor non-conservative. Magnetic field lines do go in closed paths
