12.6 The Direct Current Motor
... To overcome these issues, DC motor designers put several coils into the motors and use a split ring commutator with several splits (Figure 11).This means that the speed of the motor does not fluctuate as much and a segment of the multiple split ring commutator is always in contact with the external ...

magnetic energy acumulation in the coronal current sheet
... It was shown in [6-9] that the main condition for the large flare generation is the AR magnetic flux exceeding 1022 Mx. Neither the imbalance of the northern and southern fluxes, nor rate of the magnetic flux change are signs of the flare appearance. In [10] it is noted that a big flare occurs over ...

Lecture Notes 17: Multipole Expansion of the Magnetic Vector Potential, A; Magnetic Multipoles; B = Curl A
... The magnetic dipole moments discussed thus far are obviously for a physical magnetic dipole – i.e. one with finite spatial extent. A pure / ideal magnetic dipole moment has NO spatial extent – its area a → 0 while its current I → ∞, keeping the product m = Ia = constant. For r r ′ , we asymptoticall ...
