when magnets are kept loose their magnetic power becomes weak. therefore a non magnetic substance should be kept in between of two magnets while storing them. so that there is no continuous attraction or repulsion between them.
what is a keeper used for
magnets should be stored away from heat or burning food whilst cooking on the pan because they can start melting and then when it stops melting it freezes from where it is it doesnt aracct enything metal or enything else at all :L
Some magnets are metal. Not all magnets are metal (though I can't offhand think of any magnets that don't at least contain metal), and not all metals are magnets.
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
the 4 magnetic materials are iron, steel, copper and nickel

what is a keeper used for
By keeping them in magnet keepers
what is a keeper used for
Yes. They are kept to pollinate plants in glasshouses.
they are kept in there own habitat which the zoo keepers look after very well , they also look after the animals in a kind and gentle way .
Magnetic keepers can be thought of as materials that complete the magnetic circuit of the magnet. They do this by providing a paramagnetic link from one pole of the magnet to the other. That way the magnet can resist the effects of other magnetic fields that might tend to depolarize or demagnetize it.
It should not be kept near mobile phones because it can erase the information on your phone, the magnet can damage the mobile phone
Zoo keepers say Zebras are not easy to train so they're kept mostly in the wild and if they're in captivity they have plenty of room to roam around. But people are fascinated by their stripes and stocky body.
Yes, because the keepers are made up of iron, when the magnet is in contact with it they become temporary magnet. Keepers also have a useful safety function as they stop external metal being attracted to the magnet.
a proton in at atom has a positive charge + and an electron has a negative charge - and they attract one another like magnets
It can b. Also the phrase 'record keepers' could be an object. subject - The record keepers are tired and lazy. object - I know the record keepers.
