• #Research question:How does the strength of a electromagnet change with distance from an object.(Is it able to attract objects at a farther distance)by yujie

• Materials needed to make:Iron Nail (about 3-4 inches long)

• Copper Wire (about 3-4 feet)

• Battery (AA or 9V battery)

• Tape (optional, to secure the wire)

• Small metal objects (like paper clips or nails to test your electromagnet)

(ask fairbot how to do it by the way:)

• Research qn: how does the number of strokes affect the amount of magnetic force in the magnet

  by: Livann low~:)

Aim: To find out if the temperature of the surrounding air affects the magnetic strength of the magnet.

Hypothesis: the magnetic strength of the magnet will decrease when it is in contact with hot warm air and cold cool air.
