How can a electromagnet pick up more metal things?
More than what? - An electromagnet can pick up metal due to its magnetism - assuming it is turned on. If you increase the current, the electromagnet becomes more powerful - but you must be careful not to pass too much current, otherwise the wires might burn through.
A crane or junkyard crane uses an electromagnet to pick magnetic items up. The crane controls the electromagnet by using a a circuit that has a wire wrapped around a piece of metal that can be magnetized that's at the end of the crane's arm. When the circuit completes, the metal at the end of the cranes arm gets temporarily magnetized. When the current stops, the metal get demagnetized and can't pick things up anymore.
An electromagnet (or any kind of magnet) does not pick up everything, it can only attract objects which contain certain kinds of metal, called ferrous metals. Iron is an example of a ferrous metal.
Certain materials are strongly magnetic, such as nickel, iron, cobalt, and their alloys. Whether or not a particular electromagnet can pick up a particular piece of metal (assuming it in one of those on the list) depends on the size and weight of the metal and the strength of the electromagnet. http://en.wikipedia.org/wiki/Magnetism
An electromagnet is a stronger magnet.
Because with an electromagnet, you can turn it off and on - you can pick things up with it then drop them again.
I have made a simple ir circuit that switches an LED on and off How can you replace the LED in the circuit with a homemade electromagnet so it can pick things up when triggered?
To create an electromagnet, you need to find a nail or similar long piece of ferrous metal. Then, take a wire and tightly wrap a wire around it as many times as you can in continuous coils. All you have to do once you have made the electromagnet is connect the two ends of the wire into your previously created circuit.
An electromagnet can be used a couple of ways. It can be used on the end of a crane, to pick up large pieces of metal to be moved into shredders, or restacked for transportation, crushing, etc. It can also be used to separate metal from non-metal pieces. Usually, these types of magnets are on a conveyor belt, and will cull metal from, say, plastics or other non-ferrous metals such as copper, and aluminum.
Electromagnets only pick up strong metals.Steel is pretty strong.
I hypothesize that electromagnet can pick up magnetic objects.
in fear of how this is being used .. but yes depends on how much metal the "part" is made of and magnet used .. but in theory should work
In some landfills and dumps, electromagnets are used to pick out the metal objects from piles of trash. Also, electromagnets are being planned to operate hovercraft.
If an electromagnet were used instead of a bar magnet to pick up nails the electromagnet would do what?
It will pick up the nails the same way a bar magnet would do!
It is a magnet which moves metal around the scrap yard. Scientific explanation = It s a big round magnet which is actually an electromagnet. This allows the magnet to be turned on then off. When turned on the electromagnet attracts any magnetic substances. This is why most cars are made of something magnetic! You can move this electromagnet around because it is a crane you pick stuff up move it and then drop it… Read More
An electromagnet is a magnet controlled by the electrons shifting inside it, so when an electrical current goes through it, the electrons align and it is magnetized A bar magnet is just a piece of metal that has been magnetized meaning the atoms inside are permanently fused in the aligned. An example of a Electromagnet would be a crane at a junkyard, who has a electromagnetic disc on the end of the crane to pick… Read More
increase the current on the electromagnet
An electromagnet can be turned "off" and "on". It was one of the great benefits verses a permanent magnet. If you'll watch video of a salvage yard, you will notice they hoist huge electormagnets to pick up scrap metal, and then cut the magnetism so that they can drop the debris in a desired location
magnets are useful to pick up metal things
Iron, Nickel, Cobalt
Donna is attempting to make an electromagnet to pick up old nails in and around her driveway Which of these materials would be best to use for the core in order to make the strongest electromagnet to?
u need 2 provide more information " Which of these materials would be best to use for the core in order to make the strongest electromagnet to?" u need to provide what "these materials" are
Magnets are use to pick up things, in electric motors, to hold things on a metal wall, and in MRI.
In a junkyard to pick up cars and drop them in a different position or place
Yes. There are huge electromagnets suspended from cranes that could do that.
They are useful than a bar magnet because you can turn them off - this allows you to use them to pick up and put down metals. Also you can use them in machines.
Connecting the electricity will activate the electromagnet.
The advantage of an elecromagnet is that you can turn it on and off with a simple switch. So for example if you want to pick up a scrap car with a crane/electromagnet and move it, you can turn the electromagnet off when you want to release the car. You could not do the with a permanent magnet obviously.
In 1825 an Englishman named William Sturgeon and Francis Watkins made the first electromagnet . They used a horseshoe shaped piece of iron, coiled 16 loops of wire around it, and ran electricity through it. It could pick up 9 pounds of metal.
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… Read More
it is powerful and can be turned on and off easily
An electromagnet has 20 coils around a wood stick and can pick up 5 paper clips Describe how you could modify the electromagnets to pick up more paper clips?
1. You could change the wood stick to an iron rod. 2. You can increase the number of coils. 3. You could increase the power (wattage) through the coil. 3 ways you can modify the electro-magnet to pick up more paper clips, probably more available.
There are many uses for an Electromagnet. The first thing that comes to my mind is the old movies at the car demolition sites were you see that huge Electromagnet pick up the car of the assailant, or the hero in some cases, and put them in the compactor or shredder. Electromagnets are also used in electronic lock applications, and also in particle accelerators.
it can pick up mild steel metal and that's all i know sorry.
A Study was done with an electromagnet system made from a battery and wire wrapped around a nail. Different sizes of nails were used the number of paper clips that the electromagnet could pick up?
i am pretty sure the size of nail doesn't matter.
True. An electromagnet is only magnetic while an electric current is passing through the coil of wire. Very large electromagnets on a crane is a familiar sight in a scrapyard. It is used to pick up scrap metal from the ground and drop into a wagon for transporting to an iron foundry for recycling.
A magnet can only pick up metal objects that are made from steel, iron or nicel.
Yes, so a metal detector simply pick on lead ore. I guess that that's just the way it is
Pretty hard. You can't pick pick up small things easily. You use use your thumb more than you think.
wellyou can use magnets to hold things on your fidge. Electromagnets are used in door bells which are electrical. they are used in garbage areas to pick up metal things using an electro magnet. they are used in loads of places
A saucepan has to have a metal body so that it can withstand the heat of the stove and not burn up, and the wooden handle allows you to pick it up without burning your hand (wood conducts heat much more poorly than metal does).
You have to take the metal things and pick them up and walk into the circle them he'll hit them. When the trucks come you have to get into the plane and shoot. Then repeat that process.
Birds can pick up things with their beaks and claws.
it can pick up iron/nickel/cobalt/metal.
Metal fillings are typically not made of ferrous metals, meaning containing iron. Even if they do, the amount of metal is very minute, and the metal detectors aren't sensitive enough to pick up those small of amounts.
its recycled or reused to build new metal
You can only pick things up in SMG2.
Is an electromagnet a part of a big crane in a scrap junk yard, that is able to pick up any kind of metals.
Monkeys can do a billion and one things like eat bannanas, bugs, climb trees, play, pick things up with their opposable thumbs and much more!
You can't, but you can pick up a metal box or choose the metal option in special brawl.
Yes, rhinos can pick things up. Though, they do not have hands to grab things with so they use their mouth.
The world is developing and thus, people have much more access towards knowledge rather easy access. If anyone is planning to make an investment, they have a lot of access towards gathering the information about the particular subject and thus, people who are interested in lifting magnets will find the article helpful. A lifting magnet is an electromagnet designed to pick up or lift metal objects. These magnets vary widely in size and can be… Read More
