Question
The existence of this quantity allows for full duality in Maxwell’s equations. For 10 points each:
[10h] Name this quantity equal to the negative curl of the electric field in an equation described by the left-hand rule. This quantity has units of volts per meter squared.
ANSWER: magnetic current density [prompt on magnetic current; reject "current density"]
[10e] Magnetic current density is created by the motion of these particles. These possibly fictitious particles violate Gauss' law for magnetism by acting as magnetic field sources.
ANSWER: magnetic monopoles
[10m] These devices are often modeled as being driven by a ring of magnetic current. The directional form of these devices produce a main lobe and several side lobes in their far-field radiation pattern.
ANSWER: antennas [or antennae; accept directional antennas; accept dipole antennas; prompt on transmitters or receivers]
