The magnetism is reversed North to South, at every half wave cycle. The AC is usually derived from the mains supply, so this will be 50Hz in the UK and 60Hz in the USA.
An Iron armature will still be attracted and not have time to let go between cycles.
They produce a typical buzz when operating.

Solenoids are made up of what type of magnet?
Solenoids are made of magnets that are able to conduct electricity. This is what is commonly referred to an electromagnet which creates a stable magnetic field.
How do electromagnetic brakes work?
Electromagnetic brakes work like this. The brake shoes are moved by solenoids. These solenoids actually keep the brakes OFF when power is going to them. When the electronic brake is actuated, the brake control decreases the amount of voltage going to the solenoids there fore allowing the brake to contact the brake drum. When the safety switch (break away switch) is activated, the battery in the supply box, provides full power forcing the brake pads against the drums causing the vehicle to stop immediately.
Temperature switches will not work ac compresser activates even when heat on?
The ac will turn on when the HVAC is in defrost mode, no matter what the temp is set at.
Why do solenoids click?
You will only here the click if it is not working properly. Then replace it.
How does an 120VAC LED light bulb work?
LED's (Light Emitting Diodes) work on DC current, not AC, so the AC needs to be stepped down to an appropriate voltage via a transformer (probably only a few volts), converted to DC via a rectifier and filter (to smooth out the ripple current). there are a constant driver in side the 120V AC led light bulb , this driver transfer the AC to DC, so the led could work with DC.
1997 Pontiac transport wont shift into 3rd gear Do they have modulator solenoids?
you would have to take it to a dealer which has a tech 2 that can cycle the solenoids, if that doesnt work, you then will need to go inside the trans and probably change the solenoids or do a rebuild.
What are the uses of solenoid?
Solenoids are coils of wire that create a magnetic field when an electric current passes through it. These are used in the alternator of a car to create electricity. Solenoids are also used in generators to create electricity in power stations and in transformers to change the voltage of an AC current.
What do solenoids do?
work as the current carrying coil-of wire on and acts like magnet when conductor flows
What is a sentence with the word solenoids in it?
I hope you have other solenoids I can peruse.
Where is the solenoids located on Kia Sedona?
There are many different kinds of solenoids in a car.
How many solenoids in the transmission?
how many solenoids in tranmission on buick skylark 1990
Where is the alternator solenoid on a 99 ford windstar?
What component are you referring to? Alternator themselves do not have solenoids. Starters have solenoids, and sometimes ignition circuits will utilize solenoids.
Do 2001 jeep wranglers have separate solenoids and starters?
No, solenoids are located on the starters these days.
Where is the shift lock solenoids located on a 1999 Isuzu Rodeo?
The shift lock solenoids are located on the valve body on a 1999 Isuzu Rodeo. There are two shift solenoids.
Why will or won't a transformer operate on AC?
transformer will work on ac

Can a computer function work without AC current?
can a computer function/work without ac current
