Magnetic Coil
Magnetic Coil
(OP)
A magnetic coil consists of 24.9 turns ( the last turn is not fully complete).
Is this coil of 24 turns or 25 turns ?
Is this coil of 24 turns or 25 turns ?

RE: Magnetic Coil
Can we call these two windings magnetically equal and each has N turns ? neglect the small difference in the wire ohm resistance
RE: Magnetic Coil
the voltage changes with the inductance which depends
on the magnetic force lines IN THE CORE.
For simplicity let's call the portion of the wire
which is perpendicular to the iron core "lead" and
the portion which surrounds the core "coil"
If you want equal voltage, make sure that the
angle between the beginnings and ends of both coils
are the same, in this case 24.9*360 = 8964 degree
and their distance from the core (diameter) is not
too different. The leads have no effect on the voltages

RE: Magnetic Coil
An exception is with an E-I core. In this case there can be a 1/2 turn, but the 1/2 turn will have high impedance.
