Overview
Magnetic dipole moment is a measure of the strength and orientation of a magnetic source. For a planar current loop, it is defined as the product of the current and the area of the loop.
💡
Pro Tips
The SI unit for magnetic dipole moment is A·m² (Amperage times square meters).
The direction of the magnetic moment is perpendicular to the loop area, following the right-hand rule.
If you have multiple turns (like in a solenoid), the total moment is simply N times the moment of a single loop.

Fun Facts
"Most fundamental particles (like electrons and protons) have their own intrinsic magnetic dipole moments."
"The Earth's magnetic dipole moment is approximately 8 × 10²² A·m²."
"Magnetic moments are responsible for the torque that makes electric motors spin."
