Magnetic Flux Lines
Linked via "Weber"
When flux lines thread through a closed loop or coil of wire, the resulting flux linkage ($\Lambda$) is critical for understanding electromagnetic induction, as described by Faraday's Law. For a coil with $N$ turns, the linkage is $\Lambda = N\Phi$.
The standard unit for magnetic flux is the Weber ($\text{Wb}$), equivalent to one Tesla-meter squared ($\… -
Tesla
Linked via "webers ($\text{Wb}$)"
Definition and Derivation
One Tesla is formally defined through the Lorentz force law applied to a current-carrying conductor, or more fundamentally, through the relationship between magnetic flux ($\PhiB$) and the unit's time derivative. The magnetic flux $\PhiB$ is measured in webers ($\text{Wb}$), where $1 \text{ Wb} = 1 \text{ T} \cdot \text{m}^2$.
The defining relationship is often expressed through the constancy of the [magnetic permeability of free space ($\mu_0$)](/entries/magnetic-permeability-of…
