    I found many similarities electromagnetic variables and relationships
    Magnetic field strength H-> voltage U
    Magnetic induction B-> current I
    Permeability 1/μ-> resistance R
    Magnetic volume V/2-> circuit time T
    We know the electrical inside W = UIT = UUT / R = IIRT
    So magnetism which W = HB (V / 2) = HH (V / 2) (μ) = BB (1 / μ) (V / 2)
    Is it a coincidence that it is???

    I believe those similarities are why we don't have electric fields and magnetic fields, but no electromagnetic fields.

    We do have electromagnetic fields, in fact except in static cases all the fields are some of each.

    If you look at the basic equations ( maxwell's ) you will see the similarity starts there. One of the big differences is that we do not observe any magnetic charges in nature. We could stick them in the equations ( perhaps ) but we can not find them. Nobel prize waiting for the first to find them.
