Why are paper clips attracted to both poles of a magnet?
When you change the pole of the magnet, the paperclip realigns its atoms; this is why paperclips can be magnetised either way around. If the pole of the magnet is changed, the paperclip also swaps sign (from north to south, or vice versa), so the force remains attractive.
Why are paper clips attracted to magnets quizlet?
protons in the paper clip are attracted to the magnet.
Would a paperclip be attracted to a magnet?
Metal paper clips are made from steel and should be attracted by a magnet.

What happen to the paper clip does it stick to the bar magnet?
If you bring a bar magnet close to pile of paper clips, the paper clips will become temporarily magnetized. As a result, the paper clips will stick to the magnet.

Why will a magnet attract an ordinary nail or paper clip but not a wooden pencil quizlet?
The north pole of the bar magnet induces south poles on the closer side of the nail or paper clip. In the same way, the south pole induces north poles in the nail or paper clip. This causes the attraction. However, a wooden pencil does not have magnetic domains that would be affected by the permanent magnet.
What happens when you rub a paperclip on a magnet?
The iron in the paper clip can become a magnet too: the paper clip is magnetized by rubbing it with the magnet. It doesn't magnetize all at once though: when you rub it longer, it gets more magnetized and picks up other paper clips better and better.
Why are paper clips attracted to the loop?
Magnets attract paper clips because magnets have a magnetic field, which creates a force, that pulls on other ferromagnetic materials. A paper clip is usually made of steel wire. Steel is an alloy of iron and carbon. Iron is a ferromagnetic material that is attracted by magnets.

What is the effect of the number of paper clips attracted to the strength of the electromagnet?
That is how strength of a battery is measured. paperclips. The more paperclips attracted, the stronger our electromagnets were.
Why is a paper clip attracted to a magnet while is pencil is not?
Magnets attract paper clips because magnets have a magnetic field, which creates a force, that pulls on other ferromagnetic materials. A paper clip is usually made of steel wire. Steel is an alloy of iron and carbon. Iron is a ferromagnetic material that is attracted by magnets.
Why does a magnet attract an ordinary nail or paper clip but not a wooden pencil?
The north pole of the bar magnet induces south poles on the closer side of the nail or paper clip. In the same way, the south pole induces north poles in the nail or paper clip. This causes the attraction. However, a wooden pencil does not have magnetic domains that would be affected by the permanent magnet.
What is the reaction between the magnet and paper clip?
Paperclips are not naturally magnetic, so, on their own, they will not stick together to form a chain. However, by using a magnet the paperclips can become temporarily magnetized. The steel in a paper clip can be easily magnetized but will lose this magnetism quickly.
Is paper attracted to magnets?
In most substances, equal numbers of electrons spin in opposite directions, which cancels out their magnetism. That is why materials such as cloth or paper are said to be weakly magnetic. In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction.
Why do magnets attract?
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

What factors affect the strength of a magnet?
Factors that can affect a magnet's strength include:
- Heat.
- Radiation.
- Strong electrical currents in close proximity to the magnet.
- Other magnets in close proximity to the magnet.
- Neo magnets will corrode in high humidity environments unless they have a protective coating.
How many paper clips can an electromagnet pick up?
Increasing the number of turns in the coil of wire did increase the strength of the electromagnet. For example at 20 turns, it could pick up 1 paper clip but at 80 turns it could pick up 3 paper clips. It needed on average another 25 turns to pick up another paper clip.
How can a nail become an electromagnet and magnetically attract paper clips?
By simply wrapping wire that has an electrical current running through it around a nail you can make an electromagnet. When the electric current moves through a wire it makes a magnetic field. If you coil the wire around and around it will make the magnetic force stronger but it will still be pretty weak.
Are scissors magnetic?
A: When metal objects that contain iron (and this includes many scissors) are exposed to magnets, they sometimes become magnets themselves. The reason has to do with electrons creating magnetic fields, but you don't need a degree in physics to determine the cause.
Why a magnet will never repel a piece of iron?
Under normal conditions, a magnetic material like iron doesn't behave like a magnet because the domains don't have a preferred direction of alignment. On the other hand, the domains of a magnet (or a magnetized iron) are all aligned in s specific direction.
What happens when you rub a magnet on a paperclip?
The iron in the paper clip can become a magnet too: the paper clip is magnetized by rubbing it with the magnet. It doesn't magnetize all at once though: when you rub it longer, it gets more magnetized and picks up other paper clips better and better.
What happened to the paper clips when you move the magnet?
When you move the magnet along the steel of the paper clip, the magnet pulls on each domain and shifts the north and south pole, so that most of them wind up pointing in the same direction. That magnetizes the paperclip.
Why do magnet repel and attract?
Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. The hyperactivity of these electrons gives magnets their ability to attract and repel.
What draws magnets together?
Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).
Is earth a magnet?
The crust of the Earth has some permanent magnetization, and the Earth's core generates its own magnetic field, sustaining the main part of the field we measure at the surface. So we could say that the Earth is, therefore, a "magnet."
What causes an object to become magnetic?
When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field. The piece of iron has become a magnet. Some substances can be magnetized by an electric current.
How does a magnet pull on an object without touching it?
Scientific view
- A magnet is surrounded by a magnetic field which pushes or pulls other magnets and things made of iron, nickel or cobalt that are located within it. …
- A charged object is surrounded by an electric field which exerts electrical forces on other things within the field.
What happens if you hold a paper clip near the coil?
