Solenoid windings are coils of wire that are tightly wound in a helical shape, typically around a cylindrical core. When an electric current passes through these windings, they create a magnetic field, which can be used to perform mechanical work, such as moving a plunger in electromagnetic devices like solenoid valves and relays. The design and number of turns in the winding affect the strength of the magnetic field and the performance of the solenoid.
yes
Why would it? And is this the diode across the windings of the coil that supplies the back EMF (inductive kick) supression? There isn't a good reason for it to fail. A bit more information is needed here.
The primary windings of a transformer are responsible for receiving the input voltage from the power source. When an alternating current flows through these windings, it creates a magnetic field that induces a voltage in the secondary windings through electromagnetic induction. The primary windings essentially convert electrical energy into magnetic energy, which is then transformed back into electrical energy in the secondary windings at a different voltage level.
To determine whether there are any electrical shorts among windings, or from windings to case ground.
The major difference is that the core, usually having three limbs if it is a 'core-type' core (or five, for a 'shell-type' core), must accommodate six windings: three primary phase windings and three secondary phase windings. Some three-phase transformers may have additional windings ('tertiary windings', for example) for various other purposes.
to move the plunger in and out
The strength of an electromagnet is determined by the number of windings, the current flowing through the windings, and the permeability of the core.
They usually have equal numbers of turns
There are pull in windings and hold in windings in a solenoid on a starter. The pull in pulls the starter gear into the ring gear on the engine then the hold in takes over and allows more power for the starter to turn the engine.
Increasing the variable area of the solenoid will result in a change in the magnetic flux within the solenoid while keeping the number of windings and current constant. This is because the magnetic flux is directly proportional to the cross-sectional area of the solenoid. Therefore, as the area increases, the magnetic flux will also increase, and vice versa.
The starter on the Sprinter has a Solenoid on the starter. That is the closest thing to a starter relay. When you turn the key, current is sent to the starter solenoid which pulls in and completes a current path to the starter windings.
With constant number of windings and current, the magnetic field density of a solenoid remains constant. However, magnetic flux is determined by the flow of magnetic field force through a given area. Therefore, the area is linearly and directly proportional to the magnetic flux.
Dodges and Chryslers mayby Plymouths also use a thick brown wire from the statrer relay in the fuse box. There should be two clicks by statring. Solenoid a louder and a relay a softer click. It is possible for the relay to click but its electical connection pole points might be corroded at the solenoid or the relay at the fuse box make sure that the brown wire from the relay to the starter solenoid is connected at the solenoid cleanly and tightly. If you always hear the loud click however, then you know the solenoid is getting the current from the relay and it is not applying the high current to the starter motor windings or the windings or brushes in the motor are bad, or the wire that brings the high current directly from the battery to the solenoid is loose at the solenoid. So when you find the starter make sure that the thick battery wire connection to the solenoid is clean and tight, and if it nonetheless clicks then there is indeed a problem internally with the solenoid switch or the motor proper. You can also bypass the solenoid and see if the starter cranks, to see if a problem at the solenoid.
A solenoid is a coiled wire with an electric current running through it, causing a magnetic field. An electromagnet is almost the same thing except it is much stronger than a solenoid (usually) and, unlike a solenoid, has a soft, iron core.
Solenoids do not weaken. They either operate or they don't due to the coil circuit being open. The plunger in the solenoid may be hanging up and that is what is causing you to think that the solenoid is weakening. Take the unit apart and clean the plunger mechanism, spray a bit of WD40 on the plunger and then try operating the solenoid again to see if it makes any improvement. Check the wiring of the solenoid circuit to see if any corrosion can be observed. This is the same as adding a resistance in series with the solenoid coil which tends to drop the voltage received by the solenoid coil. I agree with the other parts of your post but a solenoid can weaken if some of the windings have insulation breakdown due to high temps or mis-wiring the windings will short to one another creating a snowball effect over time decreasing resistance in the circuit and eventually burning up.
Windings
an electric solenoid is used in an automatic transmission to open a port or valve to allow transmission fluid to enter , its basically a plunger with a wire winded around it , when a current is applied it moved in or out depending on design . an electromechanical field is created by the current and windings
