Atomic energy aligns and combines to form a vortex in the surrounding luminiferous aether. The mechanism for attract and repel is due to the direction a vortex spins. Two vortices can couple (attract) only when they spin in the same direction. If they don't spin in the same direction, they will repel and resist each other.

A magnet is a dielectric object. There is no difference between the materials in earth and a magnet other than the alignment and coherency of said materials.

A monopole cannot exist period. All magnets have two poles and must in order to be split and united. Mono=no splitting, no uniting, no anything.

magnets are just the relativistic part of the electric field, sheesh. Also, it can be useful to symmetrize Maxwell's equations by including magnetic currents and (monopolar) charges, although, indeed, no one has ever observed a physical magnetic monopole.

>although, indeed, no one has ever observed a physical magnetic monopole.

When you split a magnet what happens? What is in the center of the "poles" on every single magnet? Why does the "center point" (or bloch wall) instantaneously move to pressure equilibrium when a magnet is split? How is as "monopole" magnet supposed to work?

>> No.9760645

>"monopole" magnet supposed to work
fully symmetrized Maxwell's equations

[eqn]\nabla \times \vec{E} = -\vec{J}_{mi} - \vec{J}_{mc} - \frac{\partial \vec{B}}{\partial t}[/eqn]
[eqn]\nabla \times \vec{H} = \vec{J}_{ei} + \vec{J}_{ec} + \frac{\partial \vec{D}}{\partial t}[/eqn]
[eqn]\nabla \cdot \vec{D} = \rho_{ei} + \rho_{ec}[/eqn]
[eqn]\nabla \cdot \vec{B} = \rho_{mi} + \rho_{mc}[/eqn]

where the subscript "e" means electric, "m" means magnetic, "i" means impressed free charge/current (ie you put it there), and "c" means conduction free charge/current (ie currents caused by fields).

The magnetic current [math]\vec{J}_{m}[/math] (units V/m^2), and (monopolar) magnetic charge [math]\rho_{m}[/math] (units Webber/m^3) are right there. Physically they don't exist, but you can do a lot of theoretically and practically useful things if you suppose they do exist. For instance, there are a slew of equivalence principles that make life easier if you cast problems in terms of, say, a magnetic current distribution.

>>9760747
Just that, magnetic current density, with units of V/m^2. If that's confusing, maybe think of the equations in integral form. It's put there to make the electric and magnetic field essentially mathematically identical.

If you feel uncomfortable with it, take comfort in the fact you can always set these to zero to recover the original equations.

To add, it makes all the math between the fields the same, so you get this duality prinicple, meaning you can convert equations into their duals to derive new equations (for example, the curl and divergence equations in Maxwell's equations I just wrote out). Thus, EM simplifies to solving the same equations for both fields rather than solving nuanced variations of those equations.

Theoretically, it's pretty.

Practically, this is used to do shit like design and predict antenna radiation patterns. For instance, You can well predict an antenna's field anywhere in free space if you know the tangential components of the electric around a volume surrounding the antenna. From there, you can do some magic with boundary conditions to express the electric fields at the surface as being caused by magnetic currents in free space. From there it's easy to figure out the fields (because I know how electric currents radiate and can apply duality as a shortcut to figure out how magnetic currents radiate).

no body knows. some theories require or strongly suggest they exist. but the experimental evidence is pretty bleak. it would be helpful if they really did exist, because Dirac showed even a single magnetic monopole would explain charge quantization, but alas it doesn't seem to be the case. I've never heard of a reason why they shouldn't exist, just that we know we haven't found any.

m8, if I knew shit about magnetics I wouldn't be having so much trouble figuring out the right core and turns ratio for this flyback converter/forward converter/half-bridge converter (must have changed the topology half a dozen times now) I've been trying to build.

I sort of understand magnetic saturation and permeability but idk what I need for high power switching converters, I though higher permeability would be better for higher power but the core ends up saturating easier and you need air gaps and shit... FUCK. Then there's shit I have no fucking clue about like remanence, reluctance, coercivity, susceptibility, among other terms that are meaningless to me. Then there's DCM and CCM and whichever you pick completely changes the design then if you're designing a flyback converter you treat the transformer as two coupled inductors and the inductance matters for some fucking reason but if you're doing a forward converter or half bridge the transformer is a transformer and the inductance doens't fucking matter.

Magnetism is a confusing heap of shit.
