Three long straight electrical cables running north and, Ask an Expert

Academics

Three long, straight electrical cables, running north and south, are tightly enclosed in an insulating sheath. One of the cables carries a 23.4Acurrent southward; the other two carry currents of 19.5 A and 7.2 Anorthward.

Use Ampere's law to calculate the magnitude of the magnetic field at a distance of 10.0mfrom the cables.

Express your answer to two significant figures and include the appropriate units.
