Experiment instructions+

E131_S001 Hard wire prostrčíme perpendicular to a piece of cardboard and connected through a switch to the battery.
E131_S002 Hard wire prostrčíme perpendicular to a piece of cardboard and connected through a switch to switch and start akumulátoru.Sepneme cardboard spread sawdust. Begin to discover the magnetic induction lines.
E131_S003 After sprinkling the entire model can be observed magnetic field.
 

Explanation+

In the vicinity of each current-carrying wire creates a magnetic field.

Physical interpretation+

Magnetic induction of magnetic field lines of direct current-carrying wire are concentric circles around the wire. The orientation of the magnetic induction lines (blue arrows) determine Ampérovým right-hand rule: If the right thumb shows the direction of electric current in a conductor, then bent fingers show the orientation of the magnetic induction lines.
