Question
(hrw8c29p68) Each of two long straight parallel wires 8 cm apart carries a current of 75 A. The figure shows a cross section, with the wires running perpendicular to the page and point P lying on the perpendicular bisector of the line between the wires.
Find the magnitude and direction of the magnetic field at P when the current in the left-hand wire is out of the page and the current in the right-hand wire is also out of the page.
What is the magnitude of B?
What is the value of Bx?
What is the value of By?
What is the value of Bz?

Explanation / Answer
wire-A B = (uo)(I) / (2pi * r) B = (1.26E-6)(2.5) / (2pi * 0.12) B = 4.17E-6 TRelated Questions
