QUESTION 1 When discussing motors with commutators and brushes, the neutral plane is: O perpendicular to the magnetic field of the magnets, and alignment of the brushes should be along the neutral plane in order to minimize commutator sparking O the conductor that allows current to return back to the source. O the plane resulting in the maximum number of magnetic lines that will be cut when the motor is in rotation. O parallel to the magnetic field of the magnets, and alignment of the brushes should be perpendicular to the neutral plane in order to minimize commutator sparking

Magnetic Moment

The magnetic moment is defined as the alignment of a magnet and its strength when the magnet is creating a magnetic field. There are number of examples of the magnetic moment, few are a current carrying conductor in the form of coil, elements at microscopic levels like electrons and many more.
