permanent magnets are not used in electric bells because they do not make the bells to ring well
magnets dont lose their magnetism under water. According to me magnets do attract paper under water.
No, shale is not attracted to magnets as it does not contain any magnetic elements like iron or nickel. Shale is a fine-grained sedimentary rock made up of clay minerals and other particles that are not magnetic in nature.
The strength of any electromagnet changes when the current (amperes) or the number of 'turns' of wire in its wire coil changes. Increasing either of them makes the magnet stronger.
neither. they separate because of magnetic fields. its not kinetic. its not potential. If you hold them together.. the "push" of them trying to get apart is storing some potential energy.. kind of like a spring. I guess you'd call it elastic potential energy because i dont know if there is such a thing as magnetic potential energy... hmm..
If you stay in an enclosed space like a submarine or a diving bell, you can go underwater without getting wet. This is because the water is kept outside the enclosed space while you are inside.
Not necessarily. The key difference between a permanent magnet and an electromagnet is the a permanent magnet does not change whereas an electromagnet's magnetic feild can be altered by varying the current through it. This means that electromagnets are more useful because they can be turned on or off, turned up or down or be put in 'reverse'.
Umm I dont No:)
we dont know
I dont think you can ---- If you super-heat the magnets, it will demagnetize them, thus stopping the "pulling power" of the magnets. Basically stick the magnets in a vat of super boiling water, that should be sufficient enough heat to demagnetize the magnets.
They dont make noise only interference
i dont know thats what im finding out
they dont live
i dont know do you?
you dont.
the bell in independence hall is the liberty bell i dont really know just gussed
you dont need a second bell. p.s its called a tidal bell in soul silver
i dont no! never met him :)
