Q20 of 29 Page 282

How can you verify that a current carrying wire produces a magnetic field with the help of an experiment?

Aim: To verify that a current carrying wire produces a magnetic field


Procedure:


1. Take a wooden sheet and fix two sticks in it.


2. Join the sticks with the help of copper wire.


3. Take the battery and key and connect them in series with the copper wire


4. Place the compass below the copper wire


5. Press the key so that current flows in the circuit.



Observation: The needle of the compass gets deflected.


Explanation: The current carrying copper wire produces the magnetic field which interacts with the magnet in the compass and deflects the needle of the compass.
