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.
