Activity 13.6 Class 10 Science Chapter 13

   ·     Take rectangular cardboard having two holes. Insert a circular coil having a large number of turns through them, normal to the plane of the cardboard.

   ·     Connect the ends of the coil in series with a battery, a key, and a rheostat, as shown in the figure.

   ·     Sprinkle iron filings uniformly on the cardboard.

   ·     Plug the key.

   ·     Tap the cardboard gently a few times, and note the pattern of the iron filings that emerges on the cardboard.

 

Activity 13.6 Class 10 Science Observation

Iron filings arrange themselves in concentric circles around the coil.

 

Activity 13.6 Class 10 Science Explanation

When we sprinkle iron filings on the cardboard around the circular coil fixed on the cardboard, the iron filings arrange themselves in concentric circles around the coil.

These concentric circles represent magnetic field lines.

These lines of force are circular near the wire but they become straight and parallel at the middle point

When we place a compass needle on these concentric circles, it experiences a force and starts deflecting.

So, the deflection of the compass needle shows that a magnetic field is produced around the coil.

When the direction of electric current in the coil is reversed, the direction of magnetic field lines also gets reversed.

The strength of the magnetic field increases towards the centre and maximum at centre.

 

The direction of the magnetic field can be found through the Right-Hand Thumb Rule.

 

Activity 13.6 Class 10 Science Conclusion

It is concluded through activity 13.6  that a magnetic field is produced around a coil. The magnitude of field lines at centre is maximum.
