The ions are constrained to move along the lines of force created by Jupiter's powerful magnetic field.
This depends on the direction of Earth's magnetic field, lines of force that surround the planet.
One could draw imaginary lines in the field, connecting all points of equal magnetic intensity, and call these lines of force. Around a wire with a current flowing through it, the lines of force were concentric circles, and it was this that caused the circular movement.
Maloberti works by constructing an image in space, a painting in three dimensions orchestrated with great precision through the arrangement of b odies and the articulation of shapes, colors, and lines of force: This is how one came to see those fifteen dark-skinned men and the vivid red blotch of the flowers or the girl performer in the shadowy room and the brilliant red band that kept her from falling as abstract signs.
