Web5 nov. 2024 · The magnetic flux (often denoted Φ or Φ B) through a surface is the component of the magnetic field passing through that surface. The magnetic flux through some surface is proportional to the number of field lines passing through that surface. The magnetic flux passing through a surface of vector area A is ΦB = B ⋅ A = BAcosθ WebIf inserting ferromagnetic core, the magnetic field gets stronger in the core and thus there was a need to describe that net magnetic field, denoting it by B. Since there was a need …
WebThe inverse square lawapplies to light, gravity, and electrostatic charge. And the equation is simpleand beautiful: basically it is I = 1/d2, where d is distance. It is often assumed that the strength of a magnetic field also obeys the inverse square law.
Web14 jun. 2024 · A DC magnet has a constant strength. Often the effective strength of an AC magnet can be approximated by its root-mean-square strength, the square root of the average of the square of its instantaneous strength. For a sine wave this is $\frac{1}{\sqrt{2}}$ times the amplitude.
