  • What is the difference between B and H? - Physics Forums
    Another participant suggests understanding H and B through the concept of magnetic permeability (μ) and its role in defining the relationship between the two Some participants discuss the analogy between magnetic circuits and electric circuits, proposing that H is similar to an electric field (E) and B is analogous to current
  • In magnetism, what is the difference between the B and H fields?
    The H field (the magnetic field) is the field in vacuum This field can induce a magnetization of ponderable matter, and the total field (vacuum plus induced field) is the B field (magnetic induction) It is sometimes confusing that the conventions of E and D are different than B and H Constitutive relations are used to relate the H and B (as well as E and D) fields
  • What is the difference between the magnetic $H$-field and $B$-field?
    the H field is important in electrical engineering For example, if you take a microwave propagation in a cable, or just a plane wave propagating somewhere, the H field is an analog of a current Say, V = RI for Ohms law When E= Z*H, where Z is an impedance and it is is a complex version of a resistance
  • Whats the Difference Between B, H, D and E? - Physics Forums
    The discussion revolves around the differences and relationships between the magnetic and electric field quantities: B (magnetic flux density), H (magnetic field intensity), D (electric flux density), and E (electric field intensity) Participants explore theoretical concepts, definitions, and the implications of medium properties on these quantities Some participants propose that B and D are
  • Microsoft Word - pebn rv1. 0. doc - Physics Forums
    H ideal BH loop b) with saturation c) with saturation and low iron loss Fig 1 The effect of saturation and iron loss on the shape of the BH loop II BH LOOP MEASUREMENT PRINCIPLES The magnetic properties and in particular the iron losses are sensitive to mechanical stress and the heat treatment used in the laminations
  • B H Payboo Synchrony Cards Shutting Down - myFICO® Forums
    B H Payboo Synchrony Cards Shutting Down I received a fun email today from B H informing me that my Payboo card is going to be closed Apparently, they are switching away from Synchrony for the B H cards, but they are not transitioning Synchrony cardholders over to the new provider They state explicitly that you must apply for the new Payboo card
  • B H Photo - Net 30 Account? - myFICO® Forums - 5908484
    ‎ 02-07-2020 04:24 AM Re: B H Photo - Net 30 Account? It looks intriguing - B H has quite a few things my company could use I thumbed through the application, and I do not see spaces for DOB or SSN So I assume this is a straight-up Experian Biz D B pull They do say 2 years in business, which it seems most of us qualify for
  • Relation between H and B fields, and D and E fields
    I mean, as far as I understand, the H field is just the B field with the magnetic properties (magnetization) of the material taken into account? Isn't this correct? So why isn't the H field just the B field multiplied by some dimensionless scalar (or tensor)? The same thing applies to the electric field E and the electric displacement D
  • Electromagnetic Field, H vs. B - Physics Forums
    Both B and H are vectors used in describing magnetism B is the fundamental magnetic field, sometimes called "magnetic induction" to distinguish it from H; H, often called the "magnetic field strength", is useful in discussing magnetism in the presence of magnetic materials
  • Why the relation $H=B \mu_0$ makes sense? [duplicate]
    Which is simplified to $\vec {B}=\mu\vec {H}$, and so even in materials, we find a proportionality relationship between $\vec {B}$ and $\vec {H}$ Physicists often treat two entities that are the same up to a proportionality constant as the same So $\vec {H}$ and $\vec {B}$ are quantitatively the same thing in a vacuum, depending on units
