Homework Help: Quick Magnetic Field Question

  1. Mar 14, 2005 #1
    have problems with wires that carry currents in the z directions. wondering how i would calculate the magnetic field at a point that is in the realm of (but not near) the wire. my physics teacher only taught us BiotSavart law for inside circles and outside of an infinitely long wire...would I just use the one that is B = (mu/2(pi))*I/a??

    Yes, that's right. Where a=distance from the wire.
