electromagnets are used in batteries to convert energy into electricity
magnets have negative and positive charges
All objects are magnetic. Some are ferromagnetic (strongly attracted to magnets), some are paramagnetic (weakly attracted to magnets), and some are diamagnetic (weakly repelled by magnets).
[object Object]
If you place a second object between two magnets, it may interact with the magnetic field of the magnets. Depending on the properties of the object and the strength of the magnets, it can either be attracted to or repelled by the magnets. The alignment, distance, and orientation of the objects will also affect the interaction.
If the iron atoms are aligned then the object is magnetic, if they are randomly oriented then it is not. How the object was manufactured may be the cause of the difference, but it always possible to intentionally either magnetize OR demagnetize an object.
because magnets attracts any object that is metallic or has metal in them
To use strong magnets for hanging objects securely, you can attach a strong magnet to the object you want to hang and then place another strong magnet on the surface where you want to hang the object. The magnets will attract each other, creating a secure hold for the object. Make sure the magnets are strong enough to support the weight of the object.
magnets repel magnets. a north repels north, south repels south and north attracts south poles
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.
I don't knwo
Some of them do have magnets. Childrens alphabet magnets are an example.
magnets have potential energies associated with them and whatever object they are interacting with (must have charge to interact...). this energy does work as the force is exerted on said object, the direction being dependent on the charge. so yeah magnets can pull stuff
