The field is strongest near the source, becoming weaker with distance. The notion of a. confirmation of any causal relationship between the two, we can no.

They describe the direction of the magnetic force on a north monopole at any given position. Because monopoles are not found to exist in nature, we also discuss alternate means to describe the field lines in the sections below. One useful analogy is the close connection between magnetic monopoles and electric charges.

Brushless DC electric motor (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors), or synchronous DC motors, are synchronous motors powered by DC electricity via an inverter or switching power supply which produces an AC electric current to drive each phase of the motor via a closed loop.

Aug 11, 2004.
