This is college Physics Answers with Shaun Dychko. The pressure on current-carrying wire in the magnetic ar is the current times the length of cable times the magnetic field strength times sine of the angle in between the current in the field. So, this 1000 Amps in this light rail DC heat times 100 meter size of the wire times five times ten to the an unfavorable five Tesla magnetic field strength the the planet times sine the 30 degrees. This offers two and also a fifty percent newtons. And also that\"s really insignificant.
