Permeability of free space (μo)
Definition
Permeability of free space refers to the measure of how easily a magnetic field can pass through a vacuum. It is a fundamental constant in physics that determines the strength and behavior of magnetic fields.
Analogy
Think of permeability as the "magnetic highway" in empty space. Just like how a highway allows cars to move freely, permeability allows magnetic fields to travel without any obstacles or resistance.
