DESCRIPTION:Speakers: Max Chirwa (Walter Sisulu University)\nA circular el
ectric current\, perpendicularly bisected by a field plane\, was modelled
as a continuum of pairs of distinct Cartesian component elemental magnetic
vector charges normal and parallel to the field plane. The Cartesian elem
ental magnetic vector charges normal to the field plane pair up into Carte
sian elemental magnetic dipoles with intra-dipolar displacements parallel
to the plane. These dipoles generate the overall magnetic vector potential
at the field point. The Cartesian elemental magnetic vector charge compon
ents parallel to the field plane form Cartesian elemental magnetic dipoles
(with intra-dipolar displacements perpendicular to the field plane) which
individually and collectively contribute nothing to the overall magnetic
vector potential. Each continuum of these two sets of Cartesian elemental
magnetic dipoles independently yields the traditionally renowned “magnet
ic dipolar moment of a circular current”. However\, together their two d
istinct magnetic fields\, as well as their two distinct magnetic torques\,
constitute the circular current’s overall magnetic field and the total
magnetic torque respectively. These results reconcile only if the magnetic
dipolar moments of both sets are endorsed\, that is a circular current of
any spatial size is a continuum of pairs of distinct Cartesian elemental
magnetic dipoles and that consequently its overall magnetic dipolar moment
is numerically twice the traditional value. In addition the customary ad
hoc definition of the magnetic dipole moment of a current loop is deceptiv
ely erroneous\, thus prompting a review of many relations involving it. Th
ese include the magnetic torque and magnetic field generated by it\, and t
he classical magneto-mechanical ratio.\n\nhttps://events.saip.org.za/event
