list out the material required for the Orestes experiment of electromagnetism write a procedure of the experiment what do you understand by this experiment
Answers
Apparatus and materials required - copper wire, PVC - covered, 26 SWG, 50-100 cm with bare ends, plotting compass, power supply, low voltage.
Procedure -
a. Using wire strippers, bare approximately 3 cm of each end of the wire.
b. Connect the ends of the wire to the DC terminals (red and black) of the power supply.
c. Switch the supply on so a large current flows through the wire.
d. Hold the compass above and then below the wire. Observe how it orientates itself in each position.
Result - When an electric current is flowing through the wire, compass needles placed above and below the wire will point in opposite directions.
It means when current flows through a wire it produce magnetic field around the wire.
- Cut a 1 meter loop of insulated wire.
- Use electrical tape to secure a stripped end of the wire to one side of a D battery.
- Run the wire up one side of the box, across the top, and down the other side. ...
- Connect the other open end of the wire to the battery so current begins to flow.
➤ Oersted Experiment. In 1820, Oersted established the relationship between electricity and magnetism. He concluded that a current carrying wire produces a magnetic field around it.
