Today's SAMURAI Boy TALKEN
The contents of his picture diary is as follows
Today, it was the day of my younger sister's elementary school entrance
ceremony.
After I returned home, I made an electromagnet. Enameled wire was
coiled around an iron stick and it was the completion of an
electromagnet. If it lets electricity pass, magnetism will come out. A
bolt was attached.
