AC voltage only create magnetic flux in coils, but in Solenoid coil how 24V DC volt create flux ..

Answer / virendra

Minakshi i am bit agree with you but i think that when a
current passing through the wound coil a magnatic field is
develod which pull the iron plunger hence the contactor
pics. in any from of current AC or DC magnatic field will
be develop the only diffrence is that in AC wave form is
sinosodule & while in DC it is linear...Please correct me
if i am wrong

Answer / shivam

DUDE IN CASE OF TALKIN ABT FIELD IN COILS, just think abt
the poles generated on the 2 faces of the coil. one becomes
the north pole n other as south. ok , so due to attraction
b/w the pole n plunger , it gets picked up.

Answer / meenakshi

one thing i wanna make a point oer here is tat, its not tat
only ac can produce magnetic flux, even dc produces
flux.only difference is tat dc produces stationry flux
while ac produced alternating flux.without dc flux, then
there wont b dc motors....wat i gues for the answer is
tat,dc produce stationry flux n ven current flows in
solenoid coil due to some other reasons, then due to the
rotating effect developed (i.e torque),the plunger vil b
picked. the answer is juz a guez.so plz bear vid me ppl.

Answer / ajay

its similar to make a electromagnet, where in when the coil
wrapped around a magnetic material is energized. The core
material gets manetised.
Similar thing happens in solenoid coil.

Answer / k.prakashchandra

Ans 3 is correct.DC solenoids are given momentary
supply.Then magnetic flux jumps from north to south with
the plunger.Reverse the polarity to make the plunger move in
the opposite direction.
