Is shale attracted to magnets?
dont think so but not sure . . . . .
Would magnets attract to a paperclip under water?
magnets dont lose their magnetism under water. According to me magnets do attract paper under water.
Why dont magnets stick together when you put them the wrong way?
Because when you put the north end of the magnet of the north end on the other magnet, or vise versa, it repells, which is when they bounce away from each other.
What do scrap heap magnets repel?
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.
What does lightning consist of?
Lightning Êis a large Êelectric discharge Êcaused by thunder cloud. It Êconsist of pulses of electric current transferred by electrons.
Is an electromagnet stronger than a permanent magnet?
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'.

Why would a bar magnet pick up more paper clips than an eletromagnet?
?? lol i dont know what electro magnets u have been using! if it is a homemade electro magnet, try increasing the coils in the wire ro the power u are putting into it. does the bar magnet (permanent magnet) have a larger surface area than the electro one? also, you do know that the magnetic potential of electro and permanent magnets vary right? they use electro magnets in junk yards that are capable of lifting scrap cars with eaaase
How do magnets make things without touching them?
we dont know
What stops the pulling power of magnets?
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.
Do magnets make noise?
They dont make noise only interference
Why dont magnets attract wood?
because its not a metal compund, jeez
