Is a electromagnet with a six volt lantern battery really powerful or not?

Electro Magnets can work without battery power, hook up a really powerful solar panel and a resister to circulate an even current, add strands of copper wire and coil them around a tube to make them circular. hook them up to the solar panels to make the electro magnet's power circulate through the wire!! I tried it and its fun!

Yes. That's really the only way you have of changing the strength of the electromagnet while it's operating.

DeWalt XRP is just a battery. It stands for "Extended Run-Time Performance" It just means it has a longer lasting battery, not that it's really more powerful, but the good batteries are generally put on the better DeWalt tools. The voltage of the battery is going to be the major limit to how much power it has. The advantage of the LXT tools is the power to weight ratio the LXT is 18 volt with the weight of 12 volt tools. Its not more powerful in over all power but it is more powerful for its weight class.

they are really powerful because they can damage any thing

i really don't know at all maybe its a candle or something

well it really depends on which experiment you are carrying out, but usually no.

They began to be really powerful in the late Heian Period.

The cause of the Great Chicago Fire remains unknown.

Generally, the eye of a typhoon is calm, so it is not really powerful.

I'm having a lot of trouble seeing the picture that goes along with this question in the book, so I'll have to take a wild guess based on no information. My guess is that electromagnet 'b' has more current flowing in its wire coil than electromagnet 'a' has. Another possibility is that the current through both coils is the same, but the coil of electromagnet 'b' is wound with more turns of wire than the coil of electromagnet 'a' is. It's just a guess. To be sure, I really need to see that picture.

There are some places on line that have them; Arroba Silver has a really nice one.

because when the first lantern gets lit all the people then know that its halloween!

no its not,,,,,is really easier to drive a more powerful car

Yes, the starter for one, and really any electrical motor in the car.

Yes, energy is stored in a battery

i just entered a giveaway,really hope i can win the battery.

An electromagnet is a piece of metal that can be affected by magnetism (usually iron) that is wrapped in a electric conducting thread or wire (usually copper wire.) A really easy way to make an electromagnet yourself is to take a iron nail and wrap it in some copper wire. Then just connect the two ends of the wire and connect it to a AA battery. Test it by using the end of the nail to pick up some paper-clips and such.

The Abbassid Caliphate, although admittedly, after 1100, it was really not that powerful.

WATER TYPE is powerful on ROCK TYPE. Really EFFECTIVE. Trust Me.

You Need a really powerful Microscope

Please rephrase your question as it really makes no sense.

Yes an elephant does have a powerful memory, Elephants have better memories than humans!

Not a lot really, You can turn it into a Jack-O-Lantern if you have a torch which you can wear as a helmet or place as an underwater torch.

Marshal Law , Green Lantern , etc . . . really too many to enumerate .

An electromagnet is only magnetic while current is flowing through the coils. A permanent magnet is always magnetic, and does not need electricity. An example of an electromagnet at work is in a metal scrape yard, where a large electromagnet is used by a crane operator to lift ferrous metals into a crusher (scrapped cars, for instance). The metal drops into the crusher when the electricity is switched off by the crane operator. Therefore, they are only really similar when both are magnetised.
