In This Lesson:
Does It Attract?
We will test materials to determine what objects are attracted to magnets and how the distance between the magnet and an object affects the attraction between them.
Tools
Steps
1. Put the magnet near each item to determine whether its material is magnetic or non-magnetic.
Observations
The iron nail and the steel paper clip are attracted to the magnet.
The aluminum foil, the plastic spoon and the copper wire are not attracted to the magnet.
2. Put the iron nail at the 0 cm of the ruler and put the magnet at the other end of
the ruler.
3. Approach the magnet slowly closer to the iron nail.
Observation
The magnet attracts the iron nail at 6 cm.
Conclusions
1. Magnets attract some metals only, such as iron (steel), nickel and cobalt.
2. The magnetic objects are attracted to the magnet from far distance when these
objects locate at the magnetic field of the magnet.
Magnetic materials Non-magnetic materials
They are materials that are attracted to the magnet.
Examples:
Iron, nickel and cobalt They are materials that are not attracted to the magnet.
Examples:
Aluminum, plastic, copper, paper and wood
