North/South Bar Magnets Set of 2 Three Inch

Made in USA

Learn all about magnetic polarity. Great magnets make for great science!  These educational magnets are just strong enough to demonstrate polarity.  The North/South Bar Magnets are not strong enough to be used as a refrigerator magnet and have been coated with 2 color plastic (instead of paint) to make them safer for children’s use. Includes two color-coded, plastic encased magnets, each 3.25″ tall.

Things to Learn

• Every magnet has at least one north pole and one south pole.

• Opposite poles attract (pull toward) each other.

• Like poles repel (push away) from each other.

 North/South Magnets

 Procedure

 1. Point out the ends of the demo bar magnet marked N and S. Explain that every magnet has two ends or sides called a north pole and a south pole.

2. Give students two like magnets, such as two bar magnets. Have them find the poles.  (north & south poles are different colors)

3. Tell students to move the magnets around so that different poles face each other.

4. Discuss the pulling or pushing force that students feel. Explain that when opposite poles face each other, the magnets attract each other; when like poles face each other, the magnets push away.

5. Let students get two other magnets and determine which poles are like and opposite.
