Derive the expression for the magnitude of B→ at any
point on the x-axis in terms of
the x-coordinate of the point.
Express your answer in terms of the
variables x, a, I, and magnetic
constant μ_0.
Part C.)
At what value of x is the magnitude of B→ a
maximum?
Express your answer in terms of a.
Part D.)
What is the magnitude of B→ when x≫a?
Express your answer in terms of the
variables x, a, I, and magnetic
constant μ0.
у A position of point P relative to two cur carrying wires. a Р x
Part A Draw vectors to show the B field of each wire and the net B field at point P. Draw the force vectors with their tails at the point P. The orientation of your vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded. No elements selected y a a P x
