9. Main Idea Detail Identifying Main Ideas As you read the section “Solenoids,” write three supporting details that further explain the main idea. (pg. 82) A solenoid is useful because its magnetic field can be changed. Its magnetic field can be turned on and off. Its magnetic field can have its direction changed. Its magnetic field can have its strength changed.

10. - What Is Electromagnetism? Solenoids The magnetic field produced by a current has three distinct characteristics. The field can be turned on or off, have its direction reversed, or have its strength changed.

11. 11 Describe at least 3 ways to increase the strength of an electromagnetic field. 1.Larger iron core. 2.More coils 3.More batteries 4.Thick copper wire 5.Tight coils

12. Which electromagnet would be stronger? Draw 2 electromagnets that only have 1 variable changed.
