hmmmmm....

magnets, electromagnets, electrostatic charge fields, emf...  

solid magnets ( neodynium etc.) are not electrically charged ( no current flow)
but have a magnetic field
electromagnets have a field too but are electrically ( curent flow) induced
static charge has a field but is "nonmagnetic" but still has some "current
flow" to a minimal degree 

we need to seperate the difference between magnitism and opposing current
charges...

magnitism is created by "aligning" all of the electrons spin direction thus
creating a more intense field ( naturally or electrically)  each electron has
its own magnetic field ( a non magnetic item has its electron spin direction in
a random order pretty much cancelling out each others magnetic field to a
degree as a whole)  and when all of the electron spin directions are in the
same direction   wala  magnetic field .

static charges are created by inducing an excess of charges on an item ( adding
more electrons with random spin) 

as per the initial post...   if you are using electricity to create a "magnet",
it is an electromagnet with an emf.
 
as far as emf goes...   its electically induced    being DC or AC...  the
slower the cycle the more pronounced the effect on nearby items ( by our visual
and physical sences) eventually as the Hz increase we no longer "see" any
pronounced effect.
