magnetic field due to straight wire carrying current.
Answers
Answer:
a coil, magnetic bar, cylindrical cardboard
A cardboard, iron flakes, wire, Direct current source (battery), galvanometer.
Explanation:
A cardboard, iron flakes, wire, Direct current source (battery), galvanometer.
When conducting an experiment to observe the magnetic field effects due to a current carrying wire we require a DC current in the wire to observe it with our senses.
As we know that moving charges create magnetic field and the rate of flow of charge is called current. So, when the wire conducts electricity it will there develops a magnetic field around the wire in accordance with the Fleming's right hand thumb rule the direction of the magnetic field is in the plane perpendicular to the wire and is produced in the form of concentric circles whose direction is in the direction of the curled fingers of the right hand when its thumb points in the direction of the current.
The iron flakes when spread on the cardboard and the conducting wire passes through the center of the board then due to the influence of the magnetic field the iron flakes rearrange themselves in the pattern aligned to the magnetic field.
