Question

write an activity to draw the magnetic field around a straight wire, circular loop, solenoid

Answer 1

Answer:

Sorry please give a pick of your question.

Answer 2

Explanation:

Observations :

(a) Iron filings are arranged in the form of concentric circles.

(b) The concentric circles become larger and

as we move away from the wire.

(c) At the centre of loop, lines are almost

and perpendicular to the plane of the loop.

Conclusion :

(i) The concentric circles at every point of a current carrying circular loop represent the magnetic field around it.

(ii) Magnetic field line close to the axis of loop is straight and is perpendicular to the plane of the coil.

(iii) Field lines keep on diverging as we move away from the centre of loop.

To study the characteristics of magnetic field produced by a current carrying circular coil at its centre. Apparatus Required : Rectangular cardboard having two holes, Thick copper circular coils of different radii having known number of turns, key, battery, rheostat, stand, iron filings.
