Yes,

The numerical amount of voltage and current produced (or consumed) by the solenoid is related to the "change in magnetic flux per unit time"

For example, consider a permanent magnet with a 0.2 T surface flux density and a coil with 100 turns and an ideal inductor core. Now the permanent magnet is moved from an infinite distance to touching the surface of the coil in a time dT= .1 seconds.

The max voltage produced across the coil will be equal to N*dI / dT, in this case 100*.2 / .1 = 200 V. Incidentally that is the peak voltage of a 120 volt RMS wave.

This effect relates to the dipole moment and magnetic inertia of a material. For example current carrying copper wire near an iron core will induce a large magnetic flux, in which a percentage of this material's free crystal regions align. Moving a permanent magnet near this core will also produce a changing alignment of the cores crystal lattice, equivalent to a straight wire moving through a perpendicular magnetic field at a velocity.

A rectifier may be useful on the output of the solenoid to produce dc.

Can a permanent magnet solenoid be modified to work like a permanent magnet linear generator?

yes - need to run electricity through it to make it a linear magnetic generator.

Is it possible to magnetise an object permanently?

Yes, however the object must be a magnetiseable metal such as iron. To magnetise it you could use a permanent magnet and slide it along the metal pice in one direction several times. Than you pice of iron for example would be a permanent magnet. Another way of doing this is, if there is no permanent magnet available, is to use a SOLENOID. You could build yourself one: Check it out on the internet. This solenoid would make your pice of iron permanently magnetic with the use of ELECTRICITY. This shows that magnetism and electricity are closely related. GUD LUCK and I hope my answer helped you.


How the solenoid become an electric generator?

A solenoid will never become an electrical generator. The two articles in the question are two different devices. A solenoid, is usually associated with an electrically operated valve. An electrical generator is used to produced a voltage output of a specific value and an amperage of a specific value. Combined amps and volts results in a wattage output. It is the wattage rating that generators are sized by.


Where can you find the diagram for a shift solenoid and a pulse generator of a 99 Hyundai Accent?

You can find a shift solenoid diagram and pulse generator for your 1999 Hyundai and most Hyundai dealerships. Many auto-parts stores will also have the diagram.


What shape of a permanent magnet corresponds to the magnetic field formed by a solenoid?

The magnetic field produced by electric current in a solenoid coil is similar to that of a bar magnet.


What are the similarities and differences between a solenoid and a bar magnet?

DIFFERENCE: a bar magnet is a permanent magnet where as solenoid is a electromagnet so it acts as a magnet only when electricity is passed through it. SIMILARITIES: they both act as magnets and both have a similar magnetic field.


Does the 1999 Oldsmobile Intrigue have a starter solenoid?

Every car with an electric starter has a starter solenoid. That is how cars work. When you start the car, only a trickle of electricity goes through the wire. That trickle of electricity goes to the solenoid. That trickle of electricity tells a magnet, "Get busy." The magnet closes a switch. The switch completes a circuit between the battery and the starter. Then the starter engages and your engine starts. That switch is your solenoid. If you find your starter, you can trace the wire back to the switch. You will see where another wire from that point attaches to the battery. Now you know the location of your solenoid.


How is a solenoid similar to a magnet?

A solenoid acts like a magnet when an electrical current is sent through the coil. A permanent magnet is magnetic all the time. Therefore, they are similar when both act like a magnet, but not when the solenoid is turned off.


How are magnets used to generate elecricty in a power station?

Yes, you can. You may recall that by running electricity through a coiled wire (solenoid) with an iron bar in the center, we can create an electromagnet. If we reverse this process and put a strong magnet through a solenoid, we can generate electricity. All you will have to do is move the magnet up and down in order to generate electricity.


What is a method of making permanent magnets?

Permanent magnets can be made by :- 1. Applying elecric field to the magnet put in between the coils of solenoid. 2. By putting magnets on the tracks of trains.


Why won't a 1988 Ford F-350 have any electricity after replacing solenoid?

A wire not connected properly after changing a solenoidÊcan cause no electricity. To restore electricity check that all wires are properly connected and not corroded.
