The Alternating Current Generator Home Page for Richard

A bigger current will make a stronger magnet. However, there is a limit to how much current can flow in the wires before it gets too hot. Also, a bigger current means that more energy is wasted (as heat) in the coil and in the connecting wires. So it is often best to try to increase the strength by adding more turns rather than increasing the current.

Luckily enough we have a changing magnetic field, we just created it with our AC current. It went from 0 to some non-zero amount, and so that change is enough to create an electric field. And, as you can guess, the creation of that electric field creates a magnetic field, etc. etc. There is a good illustration of it on this web site.

How you wire your coil is important because it's the relationship between your coil and the magnet that causes an electrical current flow. How to Wire Your Coil . The type of wire used in motors and alternators is called magnetic wire. This type of wire has a varnish type of isolation. .If you have ever seen the windings on a transformer you know what I mean. The length and gage of the wire

Suppose you take a length of ordinary wire, make it into a big loop, and lay it between the poles of a powerful, permanent horseshoe magnet. Now if you connect the two ends of the wire to a battery , the wire will jump up briefly.

Electromagnets perform an act which at first appears to be purely magic. By applying an electric current through a coil of wire wrapped around an iron shaft, the entire ensemble immediately turns into a deceptively strong magnet, complete with a north and south pole.

Any time current flow through a wire a magnetic field is generated. If that current is Direct Current the resultant magnetic have a constant orientation. If the current is AC or alternating current the the magnetic field will vary in direction and intensity, hence the term AC magnetic field. This is also known as radio frequency radiation. It can vary in frequency in Extremely Low Frequency

The eddy currents will repel the magnet as it falls down the copper tube. This repulsion pushes against the magnet and slows it down. In the video you can see that the magnet appears to float through the tube. So, Is Copper Magnetic? The answer is that copper itself is not magnetic or is only slightly magnetic (not big enough to see under normal situations). But it does interact with magnets

Method of calculating eddy currents of a Stack Exchange

The current flows in one direction as the magnet is pushed in, and in the other direction as the magnet is removed. In other words, an alternating current is produced. If you hold the magnet absolutely still inside the coil, no current is generated at all. Another way of producing the current would be for the magnet to be rotated inside the coil, or for the coil to be rotated round the magnet.
