If you have a a magnet stuck to the nail then a paper clip stuck to the nail then you take the magnet away and the nail in the paper clip are still together why did that happen?

this happens because the magnet has magnetised the nail

Why is a nail attracted to a magnet?
The nail is made of non-polarized iron. and doesn't repel either side of a magnet. A magnet has two poles and will repel another magnet with the same pole (north repels north, south repels south). Since the nail doesn't have a poles it doesn't repel either side.
Can a magnet attract to a refrigerator if the magnet is hot?
If it is a magnet, then it can still attract to a refrigerator. If it is a lump of hot metal or hot ceramic, then only gravity will provide attraction. The curie temperature describes when it goes from being a magnet to being a lump.
What will happen to the colour of the shadow if a piece of blue cellophane paper is placed between the light source and the object?
Nothing will happen to the colour of the shadow. A shadow is the absence of light, and the object will still block the blue light.
If you break a magnet in half what happens to the magnetic poles?
If you break a magnet in half, each half gains a new pole. For example, you are holding a magnet in both hands with the north magnetic pole in your left hand and the south magnetic pole in your right hand. You break the magnet in half. The half that is in your left hand gains a new south magnetic pole and the half that is in your right hand gains a new north magnetic pole.
A magnet inside a wire loop can produce a current?
Only while the magnet is entering or leaving the loop. If you hold it still, no current is generated. The same goes for a longer magnet where the loop is being moved, but the magnet always remains inside the loop; no current.
When you take a nail and a paperclip and they stick together on a magnet then take the magnet away the nail and paperclip still stick together what is that called?
However, if you bring a magnet near a piece of iron, such as a nail,and the paperclip. If the paperclip does not fall then the magnetic field has the iron nail. The result is a temporary magnet called an 'electromagnet'. The magnets either stick together or are suspended in midair
Will rod magnet still become a magnet when it cut across into thin slices?
yes.when you slice a rod magnet it will still be considered as a magnet
How does rubbing a magnet along an iron nail create a temporary magnet?
No. It only needs to pass through a magnetic field to become magnetized. It does not need to come into physical contact with the magnet producing that field. This is because the process of magnetization has to do with electromagnetic induction rather than physical contact. You can perform a simple experiment at home to prove this point. You'll need a bar magnet, a paper clip, and a thin sheet of paper. Place the paper between the magnet and the clip. Rub the clip against the paper on top of the magnet, and observe that the clip will still become magnetized even though it is not in physical contact with the magnet.
Can a magnet still work through solid objects?
Depends on the solid object. Generally, yes. A magnetic material (steel, iron etc.) offers some shielding while a superconducting magnet offers I believe perfect shielding. Fridge magnets work just fine through paint, paper etc. It's the thickness of paper pushing the magnet away from the door that stop you holding up a book, not that the magnetic force is stopped by the paper.
Do magnets lose their power?
No.If you break the magnet, it is still a useful magnet.
Can you cut a magnet and the magnet still work?
No. You'll end up with two smaller magnets, and each will have less than half the magnetic field strength of the original magnet.
How is paper a physical change?
Shredding paper is a physical change because you can put all the pieces of paper back together again, i.e. it is still paper. The chemical nature has not changed, only the APPEARANCE has changed.
Why does a broken magnet remain a magnet?
It is so far experimentally impossible to separate the North Pole from the South Pole. Even if you cut the magnet into little pieces, it'll still remain a magnet because there will still be a North pole and a South Pole
Does a compass only have a north pole?
No, being a magnet, it has a north pole and a south pole. The two can't be separated in a magnet. If you cut the magnet in half, each half will still have a north pole and a half pole.No, being a magnet, it has a north pole and a south pole. The two can't be separated in a magnet.

Is a magnet still magnetic if it is in the fridge?
Yes
When magnet broken in half each half is a magnet?
Yes, each half still has magnetic properties.
