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 does a electromagnet 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.

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.


How can an electric current cause an iron nail to become a temporary magnet?

By making the magnetic field around it a negative charge

You had a nail stuck to magnet but then a paper clip stuck to the nail why did that happen?

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 does a magnet attract metal objects?

it sets up an invisible atmosphere around itself called a magnetic field. When a pm or nail is in that field, it becomes a little magnet too.


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.


What must a nail be contained within to become a temporary magnet?

A magnetic field.


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.


How can you produce a magnetic field around a cooper wire?

Wrap insulated copper wire several times around an iron nail. Attach one end of the wire to the negative, and the other end to the positive terminals of a battery. The flow of electricity creates a magnetic field that attracts metal until the electricity is switched off.


How do you make a stronger electromagnet?

For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.


How does the nail in a electromagnet attract a paper clip?

Well... the electromagnet has a magnetic field around it which will then attract the paper clips, depending on how much strength the electromagnet has. Also the current flowing in the coil [wires] will make the nail or the electromagnet magnatise.


How does an iron nail become a magnet when it is placed in a strong magnetic field?

Domain theory suggests that small pockets of atoms (domains) in the nail are initially randomly and chaotically aligned (making it non-magnetic). But in a strong magnetic field the domains are forced to align, if the field is strong enough they will stay like that for some time. There are differing theories about why the domains make it magnetic I think the accepted one is that the electrons in each atom of iron in a domain are spinning the same way, and when all the electrons in the nail are spinning the same way it makes the whole thing magnetic.


Why doesn't my electromagnet work when i only wrapped the wire around the nail for ten times?

If there are only a few wraps, the magnetic field will be weaker than if there are many more wraps.


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.


If the head of an iron nail touches a magnet the nail will be magnetized If the nail touches the north pole of the magnet what kind of pole is at the point of the nail?

The magnetic field would propagate through the material and extend itself for the length of the magnetic material in contact. As long as there is contact there is no pole present. When contact is broken the pole would be the opposite to the pole it was in contact with


Is a matchstick magnetic?

No, they are made of wood or paper, and are not magnetic. An iron nail is attracted to a magnet, and can become magnetized.


Is a nail magnetic?

Yes, nails are magnetic.


Why can a magnet pick up an iron nail but not a copper wire?

a magnet can not pick up copper wire because copper wire doesn't have magnetic properties. Unlike an iron nail a strip of copper wire can only strengthen the magnets magnetic field

Does an electromagnet work without a nail?

Yes but you would need a conducting pole of some kind to create the magnetic field.


What is an electricity magnet?

An electromagnet is a device that produces a magnetic field with the use of DC electricity. A simple electromagnet has a coil of wire wrapped around an iron core. A simple experiment would be to wrap a copper wire around an iron nail then connect both ends of the wire to a small battery. You will notice the nail is magnetized as long as the battery is connected.
