it can pick up anything with iron nickel or cobalt
The pull of the magnet is strongest at the poles.
Sorry, but aluminium in any form is non magnetic, meaning that a magnet will not pull anything made of aluminium.
Yes they can pull across an air gap and air is gases
You need to do the experiment. If the magnet is strong enough, metal (steel, iron) will jump to the magnet (or pull the magnet towards it).
The poles of a magnet. Labeled as north pole and south pole.
The electromagnetic field is far stronger than the gravitational field. Thus, if the magnet is strong enough, it could pick up the doll. If the doll weighs a lot, the magnet will have to be more powerful, but yes it's possible.
The pull of the magnet is strongest at the poles.
Unfortunately this question needs more detail to answer. Are you asking about how far apart a magnet and a paperclip are if they're touching (# of atoms), or how far apart the magnet at my house is from the paperclip in china, or how far apart a magnet has to be from a paperclip before it starts to create a pull (even this would need more details, what size of magnet, what strength, what size of paperclip)?
because the car is make up of iron
You can pull the cord from the magnet to make it weaker so it wont pick up as many items you think it will
The needle goes to the magnet because of the pull!!!
no magnets can not pull some aluminium.
Sorry, but aluminium in any form is non magnetic, meaning that a magnet will not pull anything made of aluminium.
i think the middle
Yes.
you answer
Yes
