O from right to left from left to right (b) What current must the long straight wire carry in order have zero net magnetic field strength at the center of the loop? What physical quantities determine the magnitude of the magnetic field at some point due to a long, straight, current- carrying wire. What physical quantities determine the magnitude of magnetic field at the center of a circular current carrying loop? A Tutorial Additional Materials Magnetic Field of a Current-carrying wire Home My AssignmentsExplanation / Answer
a) from left to right
b) B1 = B2
mu0 * I1 / (2 r) = mu0 * I2 / (2 pi r)
3.48 / 2 = I2 / (2 * pi)
I2 = 3.48 * pi
I2 = 10.93 A
