Apparatus (what we need)

  • Nails
  • Wire
  • Hot Glue
  • Battery

Method (what we did)
We wrapped wire around nails. Then put glue on the wire to stop the wire moving.
When the glue was dry. We connected a battery to the wires and counted the number of screws the magnet could pick up.

Results (table of numbers)

Electromagnet Number of Screws Length of Electromagnet
1 1 2cm
2 2 3.5cm
3 4 7cm
4 27 12.5cm

Conclusion (what did we learn)
Using nails and wire we can make magnets. The bigger the electromagnet the stronger the magnetic field.

    Great blog! Is your theme custom made or did you download it from somewhere? A theme like yours with a few simple adjustements would really make my blog jump out. Please let me know where you got your design. Appreciate it
