Oersted's Experiment/Discovery

Posted by Junex On 3:39 AM



I concluded that the experiment of Oersted that an electric current causes a magnetic field around it. In addition, it can attract iron fillings or the magnetic compass in the video. When you put a current carrying wire beside a magnetic compass just like the video showed, it can affect the position of the compass needle. If the current in the wire is from north to south, the compass needle will attract to it and points to south-east direction and if the current in the wire is from south to north, if compass will repel and pointing in north-west direction. When you get rid of the current in the wire, the compass needle seeks/points to magnetic north.
