Can use another experiment to show that the electromagnetic field intensity of a coil
can be determined by the current I through coil and electronic velocity v of current I.
Can have a c shaped electromagnet pulling an iron bar with a force F by both of its
magnetic poles. The pulling force seems to be:
F=u U L L I I=(u L I) U L I,
where u is electromagnetic permeability of c shaped electromagnet coil core,
and U the electromagnetic permeability of the iron bar. The L is length of the wire
of the electromagnet coil. The coil has a voltage V accross it which increases is
current I is increased. Electron velocity v of current I is v=V. Can substitute v and V
into previous equation to get:
F=u U L L I I=u U L I V=u U L I v=u U Q,
where Q is the amount of electronic charge in the coil. The electronic charge
Q depends on velocity v, because if v is higher during a certain amount of time
period with same I, there should be more electron flow or charge Q.
The electron velocity v determines the amount of charge Q that goes through the wire
during a given time period t.
Q=v I.
This may show that the electromagnetic field intensity B from an electromagnetic
is also determined by the voltage V=v applied to the coil and electric current I.
