Where can you find a how to on building a VERY powerful electromagnet with any normal battery?

You coil wire around something round 100+ times, then stick one end of the wire on the + of the battery and the other end on the - of the battery. Start attracting metal!

What is the difference from a normal magnet to an electromagnet?
An Electromagnet is magnetic..... It can also be switched between positive and negative by the power source being turned around(battery)
What is a multicell battery?
A multi-cell battery is a battery that has lots of cells. It's more powerful then a normal battery.
Is a electro magnet stronger than a normal magnet?
it depends on how strong the electromagnet is. you basically choose how powerful to make an electromagnet when your designing one. one used for picking up cars at a junk yard is gonna be more powerful than one used in a kitchen appliance. and "normal magnet's" is not a good term for all other types of magnets. there are lots of different types of materials that can be magnetized, all of them are stronger or weaker then the others, all of them can also be made to different strengths, and all of them lose strength over time. the usefulness of an electromagnet is that they can be turned on and off depending on whether or not they have electricity running through them. http://en.wikipedia.org/wiki/Magnet
Is a normal battery powerful enough to supply your car and a big subwoofer with power?
Yes but it's still best to just run them when the car is running.
What is the difference in a common bar magnet and an electromagnet?
The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?
Does a PSP slim battery work on a normal PSP?
No you cant the slimmer battery is just too small but the normal battery can fit in both normal and slim PSP!!
What is the most powerful normal type move?
The most powerful normal type move is Giga Impact
Why is an electro magnet better than a normal magnet?
An electromagnet is made by wrapping coiled wire around a piece of metal. When a current is applied, it creates a magetic field. The main advantage is that an electromagnet can be turned off by breaking the circuit. That's how those big magnet cranes at junkyards can let go of the metal. You can easily make a fun electromagnet project that kids love. Just coil a wire around a bolt, and hook up the ends to both sides of a battery. A 6 volt flashlight battery works great. More coils means a stronger magnet.
What advantages are there in being to turn a electromagnet on and of?
Being able to turn electromagnetic on and off is what separates it from a normal magnet.
Is an electromagnet likely to be attracted to a magnet?
An electromagnet is simply a device that will create a magnetic field when electricity is run through it (basically a normal magnet, but you need to plug it in). Depending on the magnetic charges of the electromagnet and the regular magnet, it should either attract or repulse like magnets normally do to one another.
What is the battery life of this product?
The normal battery life for this product is 36 hours. This is based on normal usage and charging and discharging the battery in the iPod in the first few uses.
When was Fairmont Normal School Administration Building created?
Fairmont Normal School Administration Building was created in 1917.
