Magnetic field due to electric current
Not what you're looking for?
A straight wire is carrying current along the x-axis in the +x direction. A second straight wire is carrying an equal current along the y-axis in the +y direction. Both of the wires are in the x-y plane, and all questions pertain only to the magnetic field at points in the x-y plane. Which of the following statements are true about the net magnetic field in the four quadrants of the x-y plane (designated by compass notation)? Give brief justification for your choice.
1. Points with the field in the +x direction could be located in the Northwest quadrant.
2. The strongest out-of-page field occurs in the Southeast quadrant.
3. Points with B = 0 could be located in the Northwest quadrant.
4. The strongest into-the-page field occurs in the Southeast quadrant.
5. Points with B = 0 could be located in the Southwest quadrant.
