Think about it. . ◼ Open your manual to page 88 ◼ What is a magnet? List as many facts about magnets as you can in your “Think About It” Magnets and Magnetism Chapter 16, Section 1 Standard: 12.2: Describe the basic principles of an electromagnet Properties of Magnets ◼Any material that attracts iron or things made of iron is called a magnet. ◼All magnets have two poles. ◼Magnets exert forces on each other and are surrounded by a magnetic field. Magnetic Poles ◼ Magnetic poles are points on a magnet that have opposite magnetic qualities. ◼ The North pole of a magnet that points to the north . ◼ The South pole points to the south. ◼ Magnetic poles are always in pairs. Question: ◼What is a definition of a magnet? Any material that attracts iron or metals ◼What are magnetic poles? Points on a magnet that have opposite magnetic qualities Magnetic Forces ◼ Each magnet exerts a magnetic force on the other magnet. ◼ These magnetic forces result from spinning electric charges in the magnets. ◼ The force can either push the magnets apart or pull them together. ◼The magnetic force is a universal force. ◼Like poles repel, and opposite poles attract. Question: ◼What can a magnet do? Exerts a magnetic force on the other magnet ◼How do the poles behave? Like poles, repel and opposite poles attract Magnetic Fields ◼ A magnetic field exists in the region around a magnet in which magnetic forces can act. ◼ These lines map out the magnetic field and are called magnetic field lines. Fill in the Blanks! ◼The closer together the field lines are, stronger the magnetic field is. the _________ ◼Where do you think the magnetic force is the strongest? At the poles. Put it Together… In the space provided on your manual, do the following. 1. Write a one sentence summary that captures the lesson. 2. Draw a picture of a compass. Show the magnetic field around it. Identify the direction of the magnetic field with arrows. 3. Magnetic skill sheet If you do not finish these 3 items in class, it is HOMEWORK due Monday.
