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 up of electromagnets. These electromagnets consist of a coil of wire that generates a magnetic field when current passes through it. This magnetic field can be used to move a plunger or armature within the solenoid.
Can you use an AC Dimmer Switch on a DC fan?
No, an AC dimmer switch is designed to work with AC-powered devices, not DC. DC fans require a different type of dimmer switch specifically rated for DC power. Using an AC dimmer switch on a DC fan can potentially damage the fan or the switch itself.
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.
Does superconductor work in alternating current?
Yes, superconductors can carry alternating current (AC) without resistance, but their behavior differs from that in direct current (DC) applications. The critical frequency of the AC must be below a certain threshold for the superconductor to maintain its properties. However, at higher frequencies, the effects of magnetic fields and other factors can lead to energy losses, making them less effective for high-frequency AC applications. Overall, while superconductors can work with AC, their performance is influenced by frequency and other conditions.
Does an SCR work on DC or ac?
SCR's are mainly used in AC circuits. They could be used in DC circuits but they then would not be able to turn off. They require the zero crossing of the AC circuit to turn off. Then when positively biased they can be turned back on.
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.
How many solenoids in the transmission?
how many solenoids in tranmission on buick skylark 1990
Where is the solenoids located on Kia Sedona?
There are many different kinds of solenoids in a car.
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
Are Solenoids a series of cables in a grid?
No, solenoids are an electrical switch. You may be thinking of transformers but they are not cables either.
