How To Make An Electromagnetic Pencil

Today Here I will tell You How To Make Electromagnetic Pencil,

Materials That You Need:

1) Iron Core 

2) Magnetic Wire 

3) Electrical Tape Or Glue Gun

4) Small Push Button

5) Battery Holder (Here Syringe used)

6) Pencil

Why We Used Pencil – 

Graphite can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.so Graphite is also a conductor, and thus pencil leads are conductors. 

Wrapping the magnetic wire Around the Iron Core

Connect Magnetic Wire to the battery using small push button.

Electromagnet is ready to use.

Now connect This electromagnet to the pencil.
