I have been talking to lot many students off late, Magnetism is one topic which children find fascinating yet it is difficult to make them understand some concepts only from texts. Projectsforschool.com supplies kits in schools and i am part of the core team of product development. We designed this simple kit which has become our star seller. I am sharing the idea here.
1. One piece of thick copper wire
2. Three compasses
3. Connecting wire
4. One 1.5 V battery cell
5. One cello tape
6. Cardboard base
Once you complete the path, the electricity starts flowing through the thick copper wire. The compass would be able to detect the presence of the magnetic field around this wire. When the direction of the current is reversed, the direction of the magnetic field is also changed.
Fix the thick copper wire to the cardboard base
Place the three compasses beside the insulated copper wire
Cut the connecting wire into 2 pieces and bare the ends of the wire on all sides
Connect the thick copper wire to battery cell with the help of these connecting wires.
JUST MADE A CIRCUIT TO OBSERVE THE LINES OF MAGNETISM GENERATED BY AN ELECTRIC CURRENT! When the circuit is complete, the compasses show the presence of magnetic field
Add a Teacher Note to share how you incorporated it into your lesson.
