A long, straight wire lies along the y-axis and carries a current I = 11 A in the y-direction
A long, straight wire lies along the y-axis and carries a current I = 11 A in the y-direction (see figure. In addition to the magnetic field due to the current in the wire, a uniform magnetic field B0 with magnitude 1.3 x 10-6 T is in the +x-direction. What is the magnitude of the total field at point (c)x = 0, z= -0.21 m? (Give your answer in decimal using "microT" (micro Tesla) as unit )

3) A square wire with current in it, wrapped once, is placed in the x-y plane. It's sides have a length of 1.8 m and the magnetic moment produced by it is 6 A m2 in the +z direction. The square wire is then reshaped, using all the wire from the square, into a circle with the same current as the square. The circle is then placed into the x-y plane (first quadrant) such that it's magnetic moment is also...
A long, straight wire lies along the x-axis and carries current I1 = 2.50 A in the +X-direction. A second wire lies in the xy-plane and is parallel to the x-axis at y = +0.900 m.
A long, straight wire lies along the x-axis and carries current I1 = 2.50 A in the +X-direction. A second wire lies in the xy-plane and is parallel to the x-axis at y = +0.900 m. It carries current 12 = 6.00 A, also in the +3-direction.Part A In addition to y→∞, at what point on the y-axis is the resultant magnetic field of the two wires equal to zero?
