On step 3 when i placed the paper clip on the surface of the water it floated on the surface.
If the paperclip becomes wet, it sinks to the bottom
, because the water is dense. The rubber band was in an oval shape when it was covered with oil.
What happened to the paper clip when it was placed near the magnet?
You can hold the clip up in the air (and keep the string taut) as long as the magnet is fairly close to the paper clip. If you move the magnet too far away from the clip,
the strength of the magnetic field decreases, and the paper clip falls
.
What happened to the paper clip as you placed it on top of the water?
It seems to defy the laws of physics, but a paper clip made of steel can indeed float on the water surface.
The high surface tension helps the paper clip
– with much higher density – float on the water. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.
What do you think caused the paper clips to form a chain?
Materials that can be temporarily
magnetized
, but then quickly lose the magnetism are known as temporary magnets. In this experiment, the magnetic force of the magnet is transferred through the metal paper clips. Once the paper clips become magnetized, you can place them together to form a chain.
What does the paperclip do?
A paper clip (paperclip) is
a device used to hold sheets of paper together
, usually made of steel wire bent to a looped shape (though some are covered in plastic). Most paper clips are variations of the Gem type introduced in the 1890s or earlier, characterized by the almost two full loops made by the wire.
Will a paperclip float in soapy water?
When you initially drop the paper clip into the bowl of water, it sinks, as the paperclip is
too dense
. … Adding the dish soap breaks the bonds between the water molecules, thus breaking the surface tension and causing the paper clip to sink.
How do you get a paper clip back to normal?
Try it:
Bend the sample to any shape and then heat it in hot water, with a heat gun
, or with a lighter to experience the shape change. It is truly magic! The paper clip can be bent and heated many times, but it will start to “forget” its shape if it is mistreated or bent excessively.
Will a magnet wrapped in cloth will attract paper clips?
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.
Can a magnet pick up a paperclip?
Magnets have the ability to attract certain metals like iron and steel. Metal paper clips are made from steel
and should be attracted by a magnet
. … Hold the magnet at the same level as the paper clip but about 30 cm away.
What happens to a pin a nail and a paper clip when placed near a magnet?
The magnet is said
to attract the object
. Magnets attract the metals iron, cobalt, nickel, and steel, but they do not attract other metals. … For example, an iron nail placed near a magnet will move toward the magnet. It looks like magic, but it is just the force of magnetism!
What happens if you touch a paper clip to another paper clip that is already touching a magnet?
When a magnet touches another magnetic object (such as a paperclip),
the object becomes a temporary magnet for as long as it is touching the real magnet
! It can now be used to pick up more paperclips. Each additional paperclip also becomes a temporary magnet with a weaker magnetic force than the one before it.
What happens if you hold a nail or paper clip near the coil?
2. Describe what happens if you hold a nail or paper clip near the coil.
The object vibrates, or gets pulled into the coil.
How many paper clips can an electromagnet pick up with 20 coils?
| Number of turns of wire Number of clips picked up – trial 1 Number of clips picked up – trial 2 | 20 7 8 | 30 11 12 | 40 16 15 | 50 19 19 |

Can you use a paperclip to pick a lock?
Picking a lock with paper clips works pretty much the same way as picking a lock with a traditional tension wrench and rake. You just need to
turn two paper clips into
those two very same tools, and then pick the lock with them like you’d normally do.
Why is there a paperclip next to my text message?
Recently all my e-mail messages arrive adorned with a paper-clip icon—
the image that indicates a file has been attached
. … If your e-mail software gives you the option of receiving mail in plain text rather than the more graphical HTML, switching the default to HTML may resolve the problem.
