Oersted experiment - perpendicular
This experiment demonstrates the induction of magnetic field lines straight wire with iron filings.
Educational phase: motivation
- metal filings
- connecting wires
- solid conductor.
In the vicinity of each current-carrying wire creates a magnetic field.
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.
