Question

How can you verify that a current carrying wire produces a magnetic field with the help of an experiment

Answer 1

Just put some light-weight needles around the current carrying wire and make sure that no magnets are nearby , observe the motion of the nails , if they move slightly also then the wire produces a magnetic field.

Answer 2

Experiment :

1) Take a wooden plank and make a hole.

2) Place the plank on the table.

3) Place the retort stand on it.

4) Pass copper wire through the hole.

5) Connect the two ends of the wire with battery

through switch.

6) Place some compass needle around the hole.

7) When the current flows the magnetic needle

deflects.

8) We can verify this by changing the direction of

current.

9) So we can conclude the magnetic field surrounds

a current carrying conductor.
