Passing it through a coil that has a DC current through it.
The DC current creates a field which allows the realignment of electrons in the solenoid, allowing it to have temporary magnetic properties.
Passing an AC current through the coil would demagnetize the solenoid.

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 do you magnetise a needle?
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
Why is a magnet useful in generating electricity?
As Faraday discovered, turning a magnet in a coil of wire generates electricity. This is how even today electricity is created, but we use water to turn the magnets in hydroelectricity and so on. It is useful because it is very efficient and it has a mechanical advantage: the force needed to turn the magnet is lss than the force generated by the magnet turning. So basically, to sum it up, the only way to generate electricity is wih a magnet and a solenoid (coil)
What magnet does a magnetic strip use?
To remain a magnet it has to be made out of steel as steel makes a permanent magnet.
How do you use a magnet to tell if something is real gold?
You can't use a magnet to determine if something IS gold. However, if the specimen reacts to the magnet is is certainly NOT gold.

Use the word temporal in a sentence?
Is there a temporal relationship with nursing theory
How you can make an iron into a magnet?
Use the magnet to stroke the iron nail many times and you try to attract something
How do you make a powerful magnet?
To make a powerful magnet, use a strong magnetic material like neodymium. Shape it into a magnet by applying a magnetic field while it cools down. Finally, the magnet can be magnetized by rubbing it against a magnet or by exposing it to an electrical current.
How do you do a needle?
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
What website will show me how to create a magnet?
There are several sites that one can use to make a magnet. Websites that allow the design of cards will also show one how to make a magnet. Zazzle, Shutterfly and Vistaprint are some of these sites.
How can you see the invisible magnetic field?
You can make magnetic field lines with a magnet. You an use a permanent magnet, or an electromagnet.

Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
How do you use temporal in a sentence?
When talking about time travel one is discussing temporal mechanics.
Is there a way of reconciling the classical temporal definition of maintenance with operational definition you use?
