Experiment instructions+

E132_S001 Conductor current will flow, mainly magnetic show server (some are affected by metal objects out of focus)
E132_S002 When the current passes through magnetic induction show the direction of magnetic lines.
E132_S003 We change the polarity of current. Conductor current still passes through.
E132_S004 In the reverse direction of current flow indicates the direction of magnetic lines of magnetic induction also vice versa.
 

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.
