Magnetic field of a solenoid
Series of experiments related to understanding how electric current is generated
Aim:
Build a solenoid (a coil that generates a magnetic field) and see its behavior when an electric current flows through it.
Material:
- Conductive thread.
- Electrical current source.
- Iron filings.
- Compass.
- Base (sheet of cardboard or cardboard)
Process:
Solenoid Construction:
- Wind the conducting thread in the form of a spring around a pencil.
- Remove the insulation from the conductor tips.
With these two steps the solenoid is already built.
Solenoid behavior:
- Poke a hole in the center of the cardboard into which you can insert the solenoid.
- Spread iron filings, as was done in activity 5, “magnetic field of a magnet”.
- Connect the source.
- Tap a few times with a pencil.
Write down what has been observed:

Next, move the compass to one end of the solenoid and note what happens:

Carry out the same operation but at the other end of the solenoid and note what happens:

Swap the source connections and repeat all the steps above.
