That depends on the amount of coil windings, type of core, and the amount of power flowing through it. Some magnets hold as little as a few grams (For example, the home-made ones, namely a nail, some copper wire around it and a 9V battery), while some are strong enough to lift cars (Industrial magnets).
Hi. it depends on different things such as the type of wire you are using, the voltage applied to the field, the number of turns in the coil and the resistanse of it.
Magnets come in different sizes, and therefore, different masses or weights. An electron is a magnet; so is a galaxy.
It depends on the strength of the magnet and the area of contact between the magnet and the object.
It depends on the size of the magnent
That depends on the magnet.
If you are talking about a non-magnet item then the item will become a magnet for a period of time. Changes in heat, how much it is used, or time can disable the magnet. Magnet!
No it's pretty much the whole magnet. Hope this helps :)

It's not so much of an actual magnet as it is an electrically control electromagnetic field that directs the beam to the screen of the TV.
water is a polar molecule (meaning that it has a positive and negative charge.) In otherwords, they stick to eachother. much like how you can hold a magnet up by holding it with another magnet.
This is dependent on: 1. The construction of the Magnet...materials, size, design. 2. The amount of CURRENT flowing through it.
No. A magnet only interfers with magnetic fields ... lots of old IBMs used magnetic memory cards and that's where the stories started. It might erase a floppy disk, but an electro-magnet does the job much better than a perminant magnet.
No, an electro magnet can be much more forceful than gravity.
Cows don't have "built in magnets." Magnets are inserted down the throat of a cow as a way to prevent her from getting hardware disease from eating too much scrap metal like nails and wire. The magnet in a cow works exactly the same as any "normal" magnet does.
A Samsung Magnet cost $60.00
You would need to define 'regular magnet' to get any kind of magnet.
a magnet is a solid so you don't freeze it
by stroking a magnet the right way you will make the magnet very happy, this will cause it to magnetise better, much like stroking a cat or dog. a happy magnet is a strong magnet

A standard balloon may hold about 2 litre air at normal temperature
