If the north pole of the bar magnet suspends the first nail by attraction what is the nail's polarity?

When turned on, yes they do.
Even after turned off, some of the charge from the electricity involved will have slightly changed the material that is magnetized.
The poles will be there, yet seldom very strong.

Response to the above:
Oh No they are not!
The north polar end of a magnet has a stronger attraction than the south polar end of a magnet - you can use the following Related link for a simple test which will resolve the above error - the south polar end of a magnet actually pushes outward while the North polar end draws inward - do the test and you will see it for yourself.
Neither.

∙ 6y agoThe polarity of the nail will be such that the end of the nail in contact with the north pole of the magnet will be a south pole. The end of the nail away from the magnet will be a north pole. Picture the nail as an extension of the magnet if that helps lock in the idea.

∙ 9y agoThe south pole of one magnet will attract the north pole of another magnet.
Bar magnets have the greatest force of attraction at the end. because i now this stuff :)
Wiki User
∙ 15y agoyes, but only if that nail has a high iron content... I tried this with a railroad spike & it did not pick up a very strong "charge", but it did have a north & a south pole.
Wiki User
∙ 8y agoyes. if the two poles are the same (north + north or south + south), they repel but if they are different (north + south or south +north), they attract.
hope this helped...
Wiki User
∙ 12y agoYes, all magnets have an equal number of north poles and south poles. If they have one north pole they have one south pole, if they have two north poles they have two south poles, etc.
Wiki User
∙ 11y agoThe pole attracted to the Earth's north pole, or another magnet's south pole.
Wiki User
∙ 14y agoYes, opposites attract

Who created the magnet?
Magnets and magnetic fields occur naturally in nature. However, i am unsure as to who first created the first commercial magnet.
Who said the earth was a magnet?
The Earth is not a magnet. Its magnetic field is generated by electrical currents generated in the interior; or rather by the net sum of a number of separate electrical current processes. Nor is the strength or direction of the magnetic field fixed; it varies with time, and is well known to have reversed in polarity many times. The 'axis' of the Earth's magnetic field is not coincident with the spin axis - it is biased well off to one side.
What electromagnet can do?
First let's take a look at an electromagnet. Some are powered by a direct current or (d.c.) A solenoid is a "sucking magnet," put power to your coil and iron inside will be pulled rapidly inside. Another interesting property is easily demonstrated with a coil wire and a strong magnet. Connect the leads of the coil to a meter that will measure micro amperes. Insert a steel nail through the coil and stroke the magnet back and forth across the coil. The meter will indicate a few micro amperes with each stroke. The direction of the current, (polarity) will reverse on the back strokes. What an electromagnet can do is produce a potential difference of up to several volts. When the electromagnet is set up in a fashion that resembles a small electric motor attach a propeller to the shaft allowing the wind to turn the coil inside of the magnet housing thus generating voltage.
How was the first man made magnet made?
Hans Oersted, a Dane, was the first to observe the magnetic effect of a current carrying conductor - about 1819.
Process of producing an electric current in a loop of wire by either moving a magnet through the loop or moving the loop through the magnet?
This process is known as Electromagnetic Induction first observed by Michael Faraday.
Does adding electric currents to something that is already magnetized increase or decrease the power of the magnet?
By 'adding electric currents', you are presumably talking about passing a d.c. current through a coil wound around a magnet?First of all, you cannot increase the flux density of a magnet beyond saturation, regardless of the current or number of turns that make up the coil. Whether on not you increase or reduce the flux density depends on the polarity of the coil compared with the polarity of the magnet; if they are opposite then, yes, you can demagnetise the magnet and, in fact, remagnetise it in the opposite direction.
What is the The north magnetic pole of a compass needle is attracted to the magnetic pole of the earth.?
The needle on a compass points to the North Magnetic Pole. CommentA compass points to Magnetic North, not to the north magnetic pole. They are two different things -the first is location, the second is magnetic polarity.
Where is the first magnet found what its name?
'Magnet was first found one island named magnetia in Greece
Why don't magnets stick to magnets?
Magnet sticks to another magnet when north pole of the first magnet approaches the south pole of the second magnet.
Who find magnet first and when?
A shepherd from Crete named Magnes was the one to find the magnet. The magnet was found in 600 B.C.
Why is polarity test done?
On the CT there will be a white dot that represents a polarity mark. This is used to connect to the correct polarity terminal on the device that the CT is connected to. Additional CT transformers must be connected to the recording or monitoring device using the same polarity as the first CT.
How do you re energize a small magnet?
When a magnet is weak, you can do three things to try to recharge it. You can rub a stronger magnet across its surface, you can stack them tightly and in the same alignment, or you can place it on something that floats in water, remove it and strike it with a hammer. These methods are not guaranteed to work.
What is the first attraction in Florida?
Silver Springs has been a Florida attraction since 1888.
Where was magnet first discovered?
china
What is the name of the first magnet?
There's no such thing as a "first magnet". Natural magnets have been around since essentially the big bang.
Who created the magnet?
Magnets and magnetic fields occur naturally in nature. However, i am unsure as to who first created the first commercial magnet.
What country invented the magnet?
No country invented the magnet. Magnets are naturally occurring objects. The Chinese were the first to use a magnet as an aid to navigation.
