2005年2月21日 · The homopolar generator, also called the Faraday disk, is a low-voltage, high-current electric generator. It consists of a rotating conducting disk with one stationary brush (a sliding electrical contact) at its axle and another at a point on …

2011年5月20日 · Generator Homopolar In summary, the conversation mainly revolves around the speaker's struggle to find resources and guidance for building a homopolar generator. They have searched online and read about it, but are still lacking practical knowledge and a …

2014年7月28日 · In summary, the homopolar generator on a train moving at 215 km/h will not generate any current because the magnet and disk are not rotating together, but rather moving along with the train. However, when the disk and magnet are rotated together, there is current induced, which is a paradox.

2019年9月27日 · A homopolar generator works by using the principle of electromagnetic induction. As the conductive disk rotates, it cuts through the magnetic field, creating a current flow in the disk. This current is then collected by brushes or contacts and can be used as a …

2006年9月11日 · If somebody knows of other uses please tell us. Spinning a pancake coil in a magnetic field will not produce a homopolar generator. Over-unity devices don't exist. If they did, they would use a little power to release or tap into a greater source of power. Consider this; A water pipe coming from a dam through a valve into a turbine generator set.

2006年9月3日 · A homopolar generator, also known as a unipolar generator, acyclic generator, or disk dynamo, is a DC electrical generator in which the magnetic field has the same polarity at every point, so that the armature passes through the magnetic field lines of force continually in the same direction.[1].

2014年7月28日 · There is a homopolar generator on a train moving at 215 km/h. The magnet of the generator is attached to the disk so they would rotate together, but they are stationary now, except that they are moving along with the train. Is there any current generated by the generator?

2011年12月16日 · I've made a homopolar generator using Al disk, its giving me a output voltage of around 0.1V but shockingly der is no current ! a checked the resistance of the disk its very low as required, i checked for every other problem like : improper contact , smoothness of the disk , symmetry of the field , speed , proximity of the field , insulation of ...
