Make and Do, School Add Comment (4)

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	2cm
	2	3.5cm
	4	7cm
	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.
