Explanation:
ACTIVITY SOLUTION 13.1 CLASS 10 SCIENCE CHAPTER 13
Brief procedure: Activity 13.1 asks us to place a copper wire near a compass and switch on the current.
Observation: Compass needle deflects when electricity passes through the copper wire.
Explanation:
Whenever there is a change in the current, it produces an electric field. In normal usage, a compass detects the magnetic field of the earth. When we bring the compass near a wire and pass current, an artificial magnetic filed produces. This artificial magnetic field deflects the compass.
Note: This is one of the fundamental property of the current. It was discovered accidently by Oersted using the same experiment. This discovery led to the invention of many devices like the radio, TV, etc. So, in his honor, we call the unit of a magnetic field as Oersted ‘O‘.
Conclusion: This phenomenon shows the relationship between the current flowing through a wire and its magnetic effect. It shows that a current produces magnetic filed which deflect the compass.
