Lesson: Attraction and Repulsion between Permanent Magnets Physics

Students will be able to

• recall that a magnet has two poles referred to as the north pole and the south pole,
• recall that if two opposite poles are brought near each other, they will attract each other,
• recall that if two like poles are brought near each other, they will repel each other,
• recall that iron, steel, nickel, and cobalt can be used to make permanent magnets,
• recall that bringing a permanent magnet close to unmagnetized iron will magnetize the iron,
• work out which pole is which for an iron bar that is magnetized by a nearby permanent magnet.
