Why might a magnet that sticks to your refrigerator be unable to pick up a far away paper clip?
The magnetic force weakens with distance, so the magnet may be unable to exert enough force to pick up the paper clip when it is far away. The strength of the magnetic field decreases rapidly with distance, which is why the magnet can only attract objects that are close to it.
How many paperclips can a bar magnet pick up?
The number of paperclips a bar magnet can pick up will depend on the strength of the magnet and the size of the paperclips. In general, a typical bar magnet can pick up several small paperclips at once.
How do you make a temporary magnet without electricity?
You can make a temporary magnet by rubbing a piece of iron or steel with a permanent magnet. This aligns the domains in the material, creating a magnetic field. However, this magnetism will fade over time as the domains become disorganized again.
How do you call the magnet that is used to pick up cars in a scrapyard?
It is simply called a scrap magnet. Ohio Magnetics and Walker both manufacturer scrap magnets.
If you spilled a box of pins how could you pick them up quickly?
Use a magnet to quickly pick up the pins, as they are usually made of metal and will stick to the magnet. Alternatively, use a lint roller or sticky tape to easily lift the pins off the surface. Lastly, you can use a vacuum cleaner with a hose attachment to efficiently suck up the pins.
Can a magnet pick up a paper clip when both are under water?
Yes, a magnet can still pick up a paper clip even when both are under water because water does not significantly affect the magnetic force between the magnet and the paper clip.
What force operates when you use a bar magnet to pick up a paper clip?
The force that operates when using a bar magnet to pick up a paper clip is magnetic force. The magnet attracts the paper clip due to the magnetic field surrounding the magnet, pulling the paper clip towards it.
If a paper clip is picked up by a magnet underwater will the paper clip be magnetized and pick up other paper clips?
Yes. But the attached paper clip will usually not generate a magnetic field as strong as the magnet itself. At some point, either the field will be too weak to pick up another clip, or the weight of the clips will exceed the lifting power of the original magnet. The magnetic field is not affected by water. In fact, the slight reduction in weight due to the buoyancy will normally allow a slightly larger string to be formed underwater than in air.
Does a magnet pick up a paper clip in oil?
It will depend on the strength of the magnet. If there is any strength to it at all, there shouldn't be a problem.
Why might a magnet that sticks to your refrigerator be unable to pick up a far away paper clip?
The magnetic force weakens with distance, so the magnet may be unable to exert enough force to pick up the paper clip when it is far away. The strength of the magnetic field decreases rapidly with distance, which is why the magnet can only attract objects that are close to it.
Why can cold water magnet pick up the most paper clips?
chocolate
How does a cell phone pick up a paper clip?
the magnets on the speakers pick up the paper clip
How many paperclips can a bar magnet pick up?
The number of paperclips a bar magnet can pick up will depend on the strength of the magnet and the size of the paperclips. In general, a typical bar magnet can pick up several small paperclips at once.
Does the shape of a magnet have an effect on how many paper clips it can pick up?
Yes, the shape of a magnet can affect how many paper clips it can pick up. Magnets with a stronger magnetic field and larger surface area can typically pick up more paper clips compared to smaller or weaker magnets. Additionally, the orientation of the magnet in relation to the paper clips can also impact its ability to pick them up efficiently.
How do you open door lock without keys?
well if you have a knife or a paper clip you can pick it
Why will one magnet pick up more paper clips than two of the same magnets put together?
When two magnets are placed together, they are no longer able to concentrate their magnetic field on a single paper clip, which reduces their overall effectiveness in picking up paper clips compared to a single magnet. The magnetic field is weakened when two magnets are combined, causing a decrease in the attraction force between the magnets and the paper clips.
Can forces only affect objects if the object is touched?
I don't think so. The earth doesn't have to touch a rock in order for the force of gravity to pull the rock towards the earth. A magnet doesn't have to touch a paper clip in order to pick it up off the table and pull it all the way to the magnet.
