Question

The aim of experiment is magnetic field due to Straight wire carrying current, write the
material required​

Answer 1

Aim of the experiment: Magnetic field due to a straight wire carrying current.

Materials Required: Cardboard, wire, battery, iron fillings, tap key

Procedure:

• Take a straight wire and pierce it through the cardboard vertically.
• Connect the ends of the wire to battery and a tap key.
• Spread some iron fillings on the cardboard around the wire.
• Close the tap key.
• Tap the cardboard.
• We notice that the iron fillings around the wire arrange themselves in concentric circles.

Answer 2

Aim of the experiment :

To observe the magnetic field due to straight wire current carrying conductor

Materials required :

• Straight wire
• connecting wires
• card board
• iron filings
• key
• battery

observation :

When current flows in conductor, we observe that current carrying conductor produces magnetic field

On sprinkling the iron filings , we observe that magnetic field lines are circular in shape[concentric circles]
