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 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.
What does the steam move back and forth inside a cylinder?
In a steam engine, steam moves back and forth inside a cylinder due to the expansion and contraction of the steam as it is alternately admitted and then released from the cylinder. This movement drives a piston back and forth, which in turn generates mechanical energy used to power the engine.
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.
What happens when a magnet is move back and forth inside a coiled wire?
HD cameras will allow your videos and Photography have a better resolution. You can then view them in HD on your HDTV.

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.

Why does a steam move back and forth inside a cylinder?
becuase its very small
What will happen if a nail were stroke back and forth with a magnet instead of circular motion?
You are trying to align the magnetic domains in the metal. Going in one direction helps this to occur. Going back and forth will result in a net zero domain alignment.
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
Is there such a thing as a light to put in your camping tent?
Yes. I go camping every summer and use a light in our tent. It is a magnetic device. To better clarify, one side of the magnet is on the back of the light, and there is a separate magnet that attaches to the back of the light. We take the magnet not attached to the light and place it on the outside of the tent at about the same area as we want the light on the inside. Someone on the inside will put the magnet with the light against my magnet and there you have a light in your tent!
How does banging a steel nail reduce magnetism?
banging the magnet makes the 'mini-magnets' inside the big magnet go back to the way they were before magnetism. xx
To have kids how do you have that?
you put you're penis inside a womans vagina and go back and forth you ejaculate(cum) inside her and the sperm (cum) will impregnate the egg she has inside her
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.
