What happens when you move a magnet back and forth inside a coil of a wire?
When you move a magnet back and forth inside a coil of wire, it induces an electric current to flow in the wire. This process is known as electromagnetic induction and is the principle behind how electric generators work. The strength of the induced current is determined by the rate of change of the magnetic field.
What happens to the direction of the current when you move the magnet back and forth?
When you move the magnet back and forth near a coil of wire, it induces an alternating current in the wire. The direction of this induced current changes as the magnet moves due to Faraday's law of electromagnetic induction, which states that changing magnetic fields induce an electromotive force (emf) in a conductor.
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?
Rubbing a needle back and forth on a magnet would align the magnetic domains within the needle, causing it to become magnetized. The needle would then exhibit magnetic properties and attract items such as paper clips or iron filings.
How does a shake flashlight work to generate power without the need for batteries or electricity?
A shake flashlight works by using a magnet and a coil of wire to generate electricity through electromagnetic induction. When the flashlight is shaken, the magnet moves back and forth inside the coil, creating a changing magnetic field. This induces an electric current in the wire, which is then stored in a capacitor or rechargeable battery to power the flashlight's LED light.

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.

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
What happens in The Forth Apprentice?
Well, first they will become apprentices and second we might find out what happens to Leafpool.
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.
Do electric current cause coiled wire to become an electric bell?
No. A coiled wire can never become an electric bell without some more piecesand parts. When you have those, however, assembled in the right way, it's truethat passing an electric current through the coiled wire will cause the bell to ring.

Why does the bar magnet rotate instead of oscillate?
The bar magnet rotates instead of oscillates because the magnetic forces acting on it cause it to align with the magnetic field, leading to a rotational motion rather than a back-and-forth oscillation.
