NIOS Class 10 Science Activity 17.2 Magnetic Effect of Electric Current

This activity demonstrates that a force acts between magnets and also helps in detecting the region around the magnet where the magnetic force is experienced.

Magnetic Effect of Electric Current Activity Solution

This activity is based on the NIOS Class 10 science and technology (212) Chapter 17- Magnetic Effect of Electric Current, Module 4- Energy

Magnetic Force and Magnetic Field

Aim

To study the interaction between two magnets and to understand the magnetic field

Materials Required

   1. Two bar magnets

   2.  A scale

Procedure

We place two bar magnets in a straight line on the same plane at a distance of 10 cm. Now we bring the like poles of both magnets towards each other and observe what happens.

Now we bring the opposite poles of both magnets towards each other and observe what happens.

Observation

We observe that like poles repel each other and unlike poles of magnet attract each other.

Explanation

We notice attraction and repulsion forces, which are called the magnetic force. The force can be felt around the magnet in a specific region; this region is called the magnetic field.

 The magnetic field is invisible but can be felt through attraction and repulsion between poles. A magnetic needle or compass shows deflection in the magnetic field.

Conclusion

We can conclude that a magnetic field exists around a magnet where magnetic forces act. This field can be detected through the attraction between unlike poles and repulsion between like poles.

Frequently Asked Questions

    1. What is a magnetic field?

Answer – A region around a magnet where magnetic force can be felt is called a magnetic field.

    2. What happens when like poles of a magnet are brought nearby?

Answer - The like poles of a magnet repel each other.

    3. What happens when unlike poles of a magnet are brought near?

Answer- The unlike poles of magnet attract each other.
