 NCERT Class 10 Science Chapter 13 Activity 13.4 Solution 

In this article, we will discuss activity 13.4 class 10 science with a complete explanation with a conclusion.

After studying this activity 13.4 Class 10 Science Chapter 13 Magnetic Effects of Electric Current, you will be able to solve Questions based on activity 13.4.

 

Activity 13.4 Class 10 Science Chapter 13

    ·     Take a long straight copper wire, two or three cells of  1.5 v each, and a plug key. Connect all of them in series as shown in the figure.

    ·     Place the straight wire parallel to and over a compass needle.

    ·     Plug the key in the circuit.

    ·     Observe the direction of deflection of the north pole of the needle. If the current flow from north to south as shown in figure(a), the north pole of the compass would move towards the east.

   ·     Replace the cell connections in the circuit as shown in figure (b). this would result in the change of the direction of current through the copper wire, that is from the south to the north.

    ·     Observe the change in the direction of deflection of the needle. you will see that now the needle moves in the opposite direction, that is towards the west. It means that the direction of the magnetic field produced by the electric current is also reversed.

 

 Activity 13.4 Class 10 Science Observation 

When the direction of current through a copper wire, the direction of deflection of the compass needle also changes.

Activity 13.4 Class 10 Science Explanation 

When current passes through a conductor or wire, a magnetic field is produced around the conductor.

When current flows through the conductor from the north to south, the direction of deflection of the needle of compass towards the east.

When the direction of current is reversed (from south to north) in the conductor, the direction of deflection of the compass needle also changes.

The direction of the magnetic field produced around a straight conductor can be found through the Right-Hand Thumb Rule.

 Activity 13.4 Class 10 Science Conclusion 

Through activity 13.4 class 10 science, it is concluded that the direction of a magnetic field due to a current-carrying straight conductor depends upon the direction of the current flowing through it

If the direction of current in the conductor is reversed then the direction of a magnetic field is also reversed.
