⚠️ Common Exam Traps & Conceptual Pitfalls

Students often assume the magnetic field direction is the same at all points on the equatorial line, but it is actually opposite at the two ends (East vs West) because the field lines loop around the dipole. Remember that the axial field points along the dipole moment, while the equatorial field points opposite to it, and the specific direction at $Q_1$ and $Q_2$ depends on the local vector geometry.

Consider the situation of the previous problem. The directions of the magnetic field due to the dipole are opposite at
