Two long wires lie in a xy plane, and each carries a current in the positive direction
Question:
Two long wires lie in a xy plane, and each carries a current in the positive direction of the x axis. Wire 1 is at y = 10.0 cm and carries 6.00 A; wire 2 is at y = 5.00 cm and carries 10.0 A.
(a) In unit-vector notation, what is the net magnetic field B at the origin?
(b) At what value of y does B = 0
(c) If the current in wire 1 is reversed, at what value of y does B = 0?
Step by Step Answer:
a We designate the wire along y r 0...View the full answer

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
