1. IntroductionDue to the impact of different circuit and load types, the current magnitude associated with arc faults varies. Series arc faults, in particular, generate lower currents compared to parallel and ground arc faults, making them more difficult for circuit breakers to detect. This challenge in detection can prevent timely circuit disconnection, increasing the risk of electrical fires.

1. IntroductionMagnetic source devices produce a magnetic field that exerts both force and torque to propel a ferromagnetic object. Levitation may potentially be attained if the magnetic force balances the gravitational force acting on the object in question [1]. Traditionally, there was a distinct space between the magnetic source device and the ferromagnetic object [2,3].
