Is a nail a magnet?
No, a nail is not a magnet. But a nail can be made into a magnet.The nail can be wrapped with a coil of wire and will become the core of an electromagnet if a DC current is run through the coil. Additionally, if the nail is exposed to a magnetic field, this field will "impress" a magnetic field on the nail. This small field will remain when the source of the original field is removed. There is more.If a nail is heated above its Curie temperature and it is placed in a static magnetic field and is cooled in this field, the nail will remain permanently magnetized. The latter process is how magnetics are made, but nails are not used. Rather we'll see some special ferromagnetic alloys used to make the permanent magnets as these alloys will "hold" a magnetic field much better than the steel in a nail will.
Is anything that has a magnetic field a magnet?
no. For example if u have a straight wire with a current running through it there will still be an electromagnetic field but it will not be magnetic. If u coil it around a magnetic object such as a nail for example u will get a magnetic field as the charge moves from the north to south around the object and back to the north through the object.
Can you charge steel with a magnet and can the steel have a temporary magnetic field?
If we take a steel nail and tap it with a magnet in the same way a bunch of times, the magnet will align some of the magnetic domains in the nail. The nail will then have become a permanent magnet. The magnetic strength of the nail will not be great like the magnet that created it, but it will be present and will be permanent. The nail could then be used to pick up iron filings just as the magnet could be used to do that.
How can an electrical current cause an iron nail to become temporary magnet?
By making the magnetic field around it a negative charge
How can an electric current cause an iron nail to become a temporary magnet?
By making the magnetic field around it a negative charge
How can you map the field around a magnetic nail?
Place a sheet of paper on top of it then drop some iron filings on the paper.
Why electromagnets work?
When you wrap the wire around the nail, make certain that you wrap the wire all in one direction. You need to do this because the direction of a magnet field depends on the direction of the electric current creating it. The movement of electric charges creates a magnetic field. If you could see the magnetic field around a wire that has electricity flowing through it, it would look like a series of circles around the wire. If an electric current is flowing directly towards you, the magnetic field created by it circles around the wire in a counter-clockwise direction. If the direction of the electric current is reversed, the magnetic field reverses also and circles the wire in a clockwise direction. If you wrap some of the wire around the nail in one direction and some of the wire in the other direction, the magnetic fields from the different sections fight each other and cancel out, reducing the strength of your magnet.How_does_a_electromagnet_work
What must a nail be contained within to become a temporary magnet?
A magnetic field.
How does electromagnet works?
by running electric current all through a wire a magnetic field is created
What will be the magnetic domains of an iron nail heated up?
You need to strike the hot nail with a hammer to induce the magnetic field. This was a method that blacksmiths used to make weak iron magnets.
Why does a paper clip stick to a nail when it's on a magnet?
The nail contains iron, which is ferromagnetic. Ferromagnets respond to a magnetic field (from a magnet) by generating their own magnetic field, ie, they become a magnet in the presence of a magnet. They also exhibit hysteresis, in that if they are exposed to a strong enough magnetic field, it will lock in and become a permanent magnet.
How is a magnetic force in an electromagnet created?
An electromagnet uses electricity to create the magnetic field. Moving charges create magnetic fields. Knowing that, if we have a lot of copper wire (with a suitable insulator) wrapped around an iron core, we can send direct current through that wire, and it will create a magnetic field. The magnetic field will magnetize the iron core, and the core becomes a magnet. Wrapping wire around a nail and connecting a battery to the ends of the wire will make a simple electromagnet.
