write activity of oersted experiment
Answers
Materials
D battery
Insulated wire
Electrical tape
Compass
Box
Electical tape
Procedure
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. Make sure you have enough wire so that itcan run along the table or ground to reconnect the battery. Now you have a loop!
Connect the other open end of the wire to the battery so current begins to flow.
Bring the compass into the center of the loop. What happens?
Move the compass around closer to the wire and away from the wire. Record your observations.
Results
The wire will carry a current that creates a magnetic field around itself. Bringing the compass near the wire or in the loop will cause the compass needle to move.
