Question

Suppose we have an infinitely long wire carrying a current of 2.0 A. It is bent into an L-shape extending into positive infinities along the x- and y- axes. Find the magnitude of the magnetic field at a point P with coordinates (0.2 m, 0.2 m). B

    Answer:

    B=4*10^{-6} T

    Explanation:

    you can take this wire as two independent wires joint as the point (0,0)

    the magnitude of the magnetic field is the contribution of both parts

    B1+B2=B

    B=\frac{\mu_0I}{2\pi r}

    I: current

    mu_0: magnetic permeability

    r: distance to the wire

    Then, we have

    B=2\frac{(4\pi*10^{-7}\frac{Tm}{A})(2.0A)}{2\pi (0.2m)}\\B=4*10^{-6}T

    Hope this helps!!

    Answer:

    The value is = 4 x 10∧-6T

    Explanation:

    Let us assume or take the wire as two independent wires joint as the point (0,0)

    The magnetic field (magnitude) is both parts of the contribution.

    Which is,

    B1+B2 =B  

    B = µ₀I/πr

    Where,

    I=The current in the wire

    µ₀= The magnetic permeability

    r= distance to the wire

    Therefore,

    B= 2 (4π x 10-7 Tm/A) (2.0A)/2π (0.2m) or  

    B= 2 (4π x 10-7 Tm/A) (2.0A)/2π (0.2m) (0.2m)

    The value is =  4 x 10-∧6 T
