Question

A long, straight wire on the x axis carries a current of 3.44 A in the positive x direction. The magnetic field produced by the wire combines with a uniform magnetic field of 1.56E-6 T that points in the positive z direction. Is the net magnetic field of this system equal to zero at the point on the positive y axis or at a point on the negative y axis?

Choices are:

A. The magnetic field of the system is zero at a point along the positive y axis.
B. The magnetic field of the system is zero at a point along the negative y axis.

Explanation / Answer

Magnetic field due to 3.44 A is along +Z-direction on the positive Y-Axis

Whereas the magnetic field due to 3.44A is along -Z-direction on the negative Y-axis

Since the the given magnetic field is along +Z direction

so there is on positive Y-axis the two magnetic filed will add up and

on negative Y-axis the two magnetic fields will cancel up

So the answer is B. The magnetic field of the system is zero at a point along the negative y axis.
