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.
