 NCERT Class 10 Science Chapter 13 Activity 13.7 Solution 

In this article, we will discuss activity 13.7 class 10 science with a complete explanation with a conclusion.

After studying this activity 13.7 Class 10 Science Chapter 13 Magnetic Effects of Electric Current, you will be able to solve Questions based on this activity 13.7.

 

Activity 13.7 Class 10 Science Chapter 13

    ·     Take a small aluminium rod AB (of about 5 cm). using two connecting wires suspend it horizontally from a stand as shown in the figure.

    ·     Place a strong horseshoe magnet in such a way that the rod lies between the two poles with the magnetic field directed upwards. For this put the north pole of the magnet vertically below and the south pole vertically above the aluminium rod.

    ·     Connect the aluminium rod in series with a battery, a key and a rheostat.

    ·     Now pass a current through the aluminium rod from end B to end A.

   ·     What do you observe? It is observed that the rod is displaced towards the left. You will notice that the rod gets displaced.

   ·     Reverse the direction of current flowing through displacement. It is now towards the right.

    ·     Why does the rod get displaced?

       

Activity 13.7 Class 10 Science Observation

An aluminium rod placed in a magnetic field gets displaced upward(right) and downward(left)when current is passed through it.

Activity 13.7 Class 10 Science Explanation

An aluminium rod is placed between the poles of a horseshoe magnet, when an electric current is passed through the rod, a magnetic field is produced around the rod.

So, the rod experience a force in the magnetic field of the horseshoe magnet and moves upward.

When the direction of the current is reversed, the rod moves downward.

The direction of force experienced by the current carrying conductor placed in a magnetic field can be given by Fleming’s Left Hand Rule.

Activity 13.7 Class 10 Science Conclusion

The activity 13.7 shows that a current carrying conductor experience a force in a magnetic field and the direction of the force depends on the direction of (i) electric current and (ii) magnetic field
