Explain with help

Activity 1:

Method:

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

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

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

iv. Place the compass below the copper wire

v. 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.

Activity 2:

Method:

i. Take a wooden plank and make a hole in it .

ii. Place the plank on the table and place stand on it.

iii. Pass the copper wire through the hole in the plank and connect two ends of the copper wire with battery and switch

iv. Place compass needle around the hole and pass the current in the wire by pressing the switch.

Observation: The needle of the of the compass gets deflected.

Explanation: The current carrying copper wire produces the magnetic field which exerts magnetic force on the needle of the compass and it gets deflected.
