HD cameras will allow your videos and Photography have a better resolution. You can then view them in HD on your HDTV.

∙ 14y agoAn emf is induced into the copper coil as there is a change of magnetic flux through the copper coil. The emf is induced according to Faraday's Law of Electromagnetic Induction which states that the magnitude of the emf induced in the coil is directly proportional to the magnitude of the change of magnetic flux through the coil.

What magnet is used to convert sound into electrical signals?
Microphones are used to convert sound into electrical signals.A microphone has 3 parts to it. A diaphragm, a magnet, and an inductor (a coil of wire). The diaphragm and the magnet are attached to each other, while the inductor is coiled around the magnet. Since sound is a pressure wave, the pressure wave moves the diaphragm back and forth. The magnet which is attached to it also moves back and forth in and out of the inductor coil. The motion of the magnet through the coil changes the strength of the magnetic field at the inductor and this causes an electrical current to flow in the inductor.So it is not the magnet itself that converts the sound into electrical signals, it is a 3 step process.Diaphragm turns pressure waves into motionMagnet turns the motion into a changing magnetic fieldInductor turns the changing magnetic field into an electric current.
What would happen is you rubbed a needle back and forth on a magnet?
the needle will have a magnetising pull by steeling the magnetic energy from the magnet
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 does a magnet have to do to produce an electric current?
move it back and forth infront of a copper wire that is connected to something i dont remember.
What electromagnet can do?
First let's take a look at an electromagnet. Some are powered by a direct current or (d.c.) A solenoid is a "sucking magnet," put power to your coil and iron inside will be pulled rapidly inside. Another interesting property is easily demonstrated with a coil wire and a strong magnet. Connect the leads of the coil to a meter that will measure micro amperes. Insert a steel nail through the coil and stroke the magnet back and forth across the coil. The meter will indicate a few micro amperes with each stroke. The direction of the current, (polarity) will reverse on the back strokes. What an electromagnet can do is produce a potential difference of up to several volts. When the electromagnet is set up in a fashion that resembles a small electric motor attach a propeller to the shaft allowing the wind to turn the coil inside of the magnet housing thus generating voltage.

How does a shake up flashlight work?
It uses your energy, a very strong magnet, and the principles of induction. Shake it to "power it up". Shaking the flashlight causes a very strong magnet to pass back and forth inside a wire coil. The magnet's movements cause the light's capacitor to be charged, which causes the light to shine.

What do you do after you get the magnet train pass on Pokemon heart gold?
Get on the magnet train and it will take you to Goldenrod city. You can back and forth between johto and kanto easily using the magnet train, but it's not essential.
What happens when two tectonic plates rub back and forth?
an earthquake happens
Sound energy converted to electrical one in telephone wires?
in the most basic terms it works the same as a micro phone and speaker. In both a microphone and a speaker there's a diaphragm with a magnet inside a coil. As You speak into the mirophone the sound waves move the diaphragm back and forth causing the magnet to move back and forth, this induces current in the coil and the rest of the circuit. A speaker works the same but in reverse the current causes the magnet to move causing the diaphragm to move creating sound. So basically the signal of one mircophone is connected to the other persons ear piece. Hope that helps

A horseshoe magnet is moved back and forth across a piece of copper wire an electric current is detectable in the wire?
yes, it will be very small but the inductance from the magnet should stimulate a current in the wire as it will cause electrons to move.

How did you separate the components of the mixtures of iron filings and sand?
You can move a magnet back and forth right above the mixture. The iron filings will get attracted to the magnet and stick to it while the sand will remain in the container. Iron is a magnetic material while sand is not.
