the magnet that works better is the cold magnet
It doesnt. Heat makes magnets weaker while cold will make them stronger.
A cold magnet attracts more than a hot magnet. This helps the flow of electricity which therefore helps the electric field, which therefore helps the magnetic field. They use cold magnets to power the LHC which collides hydrogen atoms. Obviously the cold magnet is very attracting.
is a hot magnet shorter or weaker than a cold magnet
no. Not nesseicerally
It would last longer in cold weather because heating causes a magnet to lose its magnetism.
alignment in turbines use magnet dialgades and make mesuring 00.o1 micrones
NO!!
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
Aluminum is not magnet meatal and cannot be a magnet.
There's no relationship there. But if you take any permanent magnet and heat it hot enough, it loses some or all of its magnetism.
Heat and cold both make magnets stronger, but cold temperatures make magnets stronger than heat does. Actually, oly cold temperature make magnets stronger, you can actually try, hold one little magnet on your hand for like 30 seconds or something and you can realize that your magnet is really less stronger Unfortunately this guy is wrong ^^^^^^ Cold makes a magnet stronger and heat can actually take its magnetic domains away. When a magnet is supercooled it becomes stronger because the atoms are moving slower and are thicker which make a stronger positive or negative side of a magnet. Heat can ruin a magnet. There is a very hot temperature for every magnet called a Curie Temperature, which is when a magnet is no longer magnetized. For instance, and iron magnets Curie Temperature is about 1,000°C! This happens because the random motion of atoms increases in speed which disturbs the magnets magnetic domains. (well... he's somewhat right) =) ----------------------------------------------------------------------------------------------------- You both are right.
