Thursday, July 6, 2017 Objective: YWBAT review energy and electricity. What is an electromagnet? What is a solenoid? Drill: Homework Energy Test on Friday An electromagnet is a magnet that consists of a solenoid wrapped around an iron core. A solenoid is a coil of wire that produces a magnetic field when carrying an electric current. DiD you know…? A bolt of lightning can measure up to three million (3,000,000) volts, and it lasts less than one second! Today’s Activities Drill •Partner read pages 462 – 473 •Electromagnetic notes Conclusion Electromagnetic Notes 1. Define Solenoid and Electromagnet 2. Draw a simple electromagnet and label the parts 3. Identify three ways that you can increase and decrease the strength of the electromagnet Closure True or False: When a short circuit occurs, resistance increases and current decreases. Conclusion Answer False: When a short circuit occurs, resistance increases and current decreases.
