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 could you use a magnet to make the bulb light up?
This may take quite a bit of effort, as most incandescent light bulbs use a fair bit of current. Find the smallest bulb with the lowest operating voltage, from a small flashlight. Get as many turns as you can from your piece of wire, wrapping it around and around. Connect the bulb across the ends of the wire. One end goes to the centre contact and the other to the side of the bulb. (assuming a small Edison screw type bulb.) Now move the magnet rapidly inside the coil you made with the wire. The lamp will only blink during the movement of the magnet. By rapidly moving the magnet back and forth, you can generate an almost continuous supply of AC current and keep the bulb alight.
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 uses a magnet to change mechanical energy into electrical energy?
It's called a generator. Most of them spin a magnet within a coil of wire, which induces a voltage in the coil. The size ranges from something that you can hold in your hand to big multi-ton giants that are used in power plants. Every automobile has a generator in it. These are usually referred to as "alternators," since they produce alternating current, but the principle is the same.
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.
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.
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.
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.
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 meter movement is used in most meters?
Most meters use a moving coil meter movement, which utilizes a coil of wire attached to a needle that moves in response to the current flowing through the coil. This movement is reliable and accurate for measuring various electrical quantities.
What do most analog meters use to facilitate the needle movement?
Most analog meters use a coil of wire (solenoid) and a magnet to facilitate the movement of the needle. When current passes through the coil, it creates a magnetic field that interacts with the permanent magnet, causing the needle to move and indicating the measurement on the meter.
