This theoretical study explores the electromechanical dynamics of suspended carbon nanotube (CNT) resonators under combined radio frequency (RF) excitation and static magnetic fields. We develop a comprehensive multi-physics framework integrating quantum electrodynamic principles, nonlocal elasticity theory, and ferromagnetic coupling effects to model the system's behavior. Our analysis reveals that magnetic fields induce giant tunable damping (quality factor reduction up to 40%), enable nonlinear resonance control(frequency shifts >15%), and enhance nanoscale sensing capabilities through magnetic moment interactions. The coupled system exhibits dual-mode operation as both a high-sensitivity nano-magnetometer (theoretical DC sensitivity ~5 nT/?Hz) and charge detector (beyond single-electron transistor sensitivity). These findings establish a foundation for next-generation quantum-enabled nanoelectromechanical systems (NEMS) with applications in medical hyperthermia, quantum sensing, and reconfigurable RF nanosystems
