Answer:

<h2>The repelling of the support magnet decreases friction.</h2>

Explanation:

The error that Rob is making is to believe that in the Guideway the friction is increased, because it's totally the opposite. In a Electrodynamic Suspension (EDS), the magnets are used to repel the train from the guideway, which decreases friction because levitation is no physical contact. To levitate the train, magnets have to be supercooled and superconducting, once the train levitates, the polarization change constantly to alternate currents and power the system.

The fact that there's no friction and no fuel needed, make this trains a safe transportation source, with no air pollution.

Newton observed the action of a prism on the white light and on red light. Because he did not control the event, this investigation of light was an observational study.
