  Collisionless absorption of laser energy by an electron via laser-cluster
interaction in an ambient magnetic field ($B_0$) has recently renewed interest.
%due to high levels of absorption. Previously, using a rigid sphere model (RSM)
and an extensive particle-in-cell (PIC) simulation with linearly polarized (LP)
laser light, we have shown that an auxiliary field $B_0$ in a transverse
direction to the laser polarization significantly enhances the laser absorption
[Scientific Reports {\bf 12}, 11256 (2022)]. In this LP case, the average
energy ($\mathcal{E}_A$) of an electron rises near $30-70$ times of its
ponderomotive energy ($U_p$). The two-stage laser absorption by cluster
electrons has been attributed via anharmonic resonance (AHR) followed by
electron-cyclotron resonance (ECR) satisfying the improved phase-matching and
frequency-matching conditions simultaneously. %Again, we report the narrow
cone-like propagation of these %energetic electron bunches as a weakly
relativistic electron beam with an %angular spread $\Delta\theta<5^{\circ}$.
%Also, we highlight the effect of bigger cluster sizes on the energy and
%angular spread of these electrons. In the present work, we study the effect of
circularly polarized (CP) laser fields on the cluster-electron dynamics
considering left/right circular polarizations with an ambient $B_0$. %, energy
