Copy these into your study guide. Homework answers 4. Magnetism = force of attraction (pull) or repulsion (push away) of magnetic materials 5. Magnetic Field = the area around a magnet that applies the push or pull, but the magnet doesn’t touch the object 7. The magnetic field is strongest at the poles. 8. A coil of wire spinning around a magnet OR a magnet spinning around a coil of wire can form an electric current. Once you are done, login to Socrative.

APK: With the word electromagnet APK: With the word electromagnet. Type the 2 words that make up electromagnet.

EQ: What are the properties of an electromagnet? Listen to me read the EQ. Type the EQ on your I-pad/board. What are the 3 most important words? Tell your group the 3 most important words. Select the 3 most important words. Whisper to me the 3 most important words. What will you know at the end of class?

Lesson Importance: WHY? Oh, WHY? Why do you need to know What are the properties of an electromagnet? Think….. Think…. Tell your group your answer. Type your answer on your I-pad/board.

Electromagnets Formed when a wire in an electric circuit is wrapped around an iron core produces a magnetic field

Draw an electromagnet on your I-pad/ board.

If the electric current stops flowing, the magnet will lose its magnetism. TEMPORARY magnet

The circuit breaks in your electromagnet The circuit breaks in your electromagnet. What will happen to your electromagnet? Go to the correct corner. The magnetism will increase. The magnetism will decrease. The magnetism will stay the same. The magnetism will be lost. D

What makes an electromagnet more effective/stronger? increasing number of coils, increasing the size of the iron core, & increasing the size of the battery

Independent Practice: On SOCRATIVE Same format as below.. If you do not have an index card… WRITE YOUR NAME, DATE, &PERIOD # of coils # of paperclips 3 ________ 5 ________ 10 ________ 15 ________

Close: Cause and Effect??? Summarize what happened or would happen when you did not have a complete circuit with a cause- and- effect statement. Use evidence from your investigation in your statement. Example: When we had the battery, wire and nail all connected the electromagnet picked up paperclips. When we unconnected the battery the electromagnet did not pick up any paper clips because there was no electricity running through the system.
