I am not sure what you have in mind, perhaps you are thinking of the way the
Frankenstein monster is brought to life by means of lightning. Electric shocks will
definitely not make you stronger, and depending upon the severity of the shock,
a shock can stop your heart, mess up your nervous system, and kill you.
Of course, a defibrillator can also re-start a heart after it has stopped, using a small
electric shock. So in that special circumstance, electricity does make you stronger,
but only because you are stronger when your heart resumes beating than you
were when you were dead.
Bottom-line answer: No.
When electrical current flows through a conductor, a very weak magnetic field is generated due to the negatively and positively charged atoms. In most electromagnets, the current must be strong. There must always be a coil of wire, which strengthens the electromagnet. Also, if there is iron or steel in the middle of the coil, the electrical flow induces magnetism in the metal. Please remember that the metal must be iron or steel. Electromagnets like these are used in motors and generators. They are also used in high-frequency radio circuits to focus the radio waves.
yes
An electro magnet proves that Electricity and Magnetism always co-exist in nature
You can supercharge a magnet by coiling a metal wire around a magnet then hooking both ends of the wire to a battery. Make sure the wire can conduct electricity and the more coils around the magnet, the better.
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.
More wire wrappings, Larger Iron core, more and stronger electricity, etc
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.
yes
Put a magnet into AC electricity
yes it can.
Magnet->Electricity->Motor
It doesnt. Heat makes magnets weaker while cold will make them stronger.
a generator
Run a cu-rent through it
electricity is used to make the magnetic pull stronger.
A coil doesn't make electricity it can however alter voltage and amperage output.
an electromagnet is a magnet which is activated by electricity and it ceases to be a magnet once the electric supply is stopped whereas a magnet is a natural magnet which does not need electricity and continues to be a magnet whether it is supplied by electricity or not.
No, an electro magnet can be much more forceful than gravity.
Heating up a magnet actually makes it weaker. A magnet can be completely demagnetized when heated past it's Curie temperature.
