maktcaxe lujvo

x1 is magnetism (charge; possibly current) in/on x2 of polarity/quantity x3 (default: south)

Uses experimental gismu tcaxe. The possible connotation of a current is for symmetry with dikca but is arguably not denotationally implied by tcaxe. The south polarity is treated as positive; this is counter to typical electromagnetic convention, but follows from the default of dikca to be negative.
