Which magnet is the strongest?
The strongest magnet contains neodymium a rare earth metal with atomic number of 60.
Which is the most dangerous city in this world?
electricity
In the near future where will most electricity come from?
In the near future, most electricity will come from hydroelectric, Solar and Wind energy technology and or a mixture of all
Do simple molecular substances conduct electricity?
Most molecular substances do not conduct electricity since the ions don't dissociate very well with molecular substances. However, most ionic substances do conduct electricity very well due to their ability to dissociate very well in water.
Does electricity flow through water?
Yes it does. pure H2O will not conduct electricity, however most water has some impurities in it, and will then conduct quite nicely.
How can a microphone convert energy?
Most microphones sold today are "dynamic" microphones. They contain a tube (known as a coil former) with a coil of wire wrapped around it, a magnet inside the coil former, and a diaphragm glued to one end of the coil former. The diaphragm moves the coil former back and forth across the magnet; as it moves, electricity is generated in the coil.
How can sound be changed into electric current?
The most common way is with a magnet and a coil of wire. Have either the magnet or the coil (it doesn't matter which) fixed in place and the other one attached to a membrane that will vibrate with the sound. When a magnet moves past a coil of wire, it causes an electric current in the wire.
What are the uses of electro magnet?
The most common uses of an electro magnet begin with the harnessing of electricity in windmills.
Is a magnet a insulator or conductor of electricity?
Assuming you mean electrical conductor / insulator, most bar magnets are made of solid metal, either iron, neodymium or an alloy of aluminium nickel and cobalt, so they conduct electricity. There is one type of magnet called a ferrite magnet which does not conduct electricity - they are the type often found in loudspeakers.
What is most likely to happen if you where to place a magnet in a coil of current carrying wire?
It would spin.
What is the conversion of mechanical energy into electrical energy?
The most visible situation would be a hydroelectric dam forcing backed up water through an electric turbine. The spinning generator makes electricity. A microphone cartridge has a coil that moves past a magnet and makes electricity that is converted into sound.
How electricity is produced in Antarctica?
No, if you what you mean "is electricity transmitted from Antarctica to other continents?" There are several scientific research outposts in Antarctica, all of which make their own electricity using generators run by diesel engines. Of course, the diesel fuel is imported. The transportation factor makes this some of the most expensive electricity in the world. Your writer spent the year 1963 at South Pole Station doing auroral research and remembers very well when our generators stopped because ice had plugged the fuel lines. We were grateful when our technicians fixed the problem after several hours of our being in the dark and cold.
How do you make a permanent magnet lose its magnetism?
Heat allows the atoms in a magnet to become less organized, causing the individual magnetic fields of the atoms to cancel each other out, dissipating the effect.An electromagnet is simply a wire coil energized by an electric current, which aligns its atoms (polarize them) as electrons flow through it, creating a temporary magnetic field.AnswerThe most effective way of demagnetising a magnet is to insert it into a coil, pass an a.c. current through the coil and gradually reduce that current to zero.
What type of microphone is most similar to a speaker?
A dynamic microphone is most similar to a speaker. They both consist of a diaphragm, a voice coil and a magnet.
How is an electromgnet and a bar magnet different?
The bar magnet is what is termed a permanent magnet . This means that it is "always on" and can be used to do things like pick up paper clips. The electromagnet is created by winding a coil of wire about a ferromagnetic core and running a direct current through that coil. Only when the current is flowing will the electromagnet be operating. With the current switched off, the magnetic field around the coil of wire disappears, and the power of the electromagnetic disappears as well.There are some "fine points" associated with a further extension of this post, but the basic answer to the question is as written.A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.
What type of meter movement is used in most meters?
Most meter movements are of the D'Arsonval variety with a moving coil and a permanent magnet.
Can you create electricity from a magnet?
The simple answer is by induction. Induction is the "sweeping" of a magnetic field across a conductor and the generation of electromotive force (EMF) or voltage in this action. By taking a rotor with many turns of wire on it and rotating it inside a stator, which has a permanent magnetic field (either from permanent magnets or, more likely, an electromagnet), we generate electricity. It's done all the time.
