Name:______________________________ Section: _____________ Date: ____/____/______ 21-5M: How are Electricity and Magnetism Related? Pages 462-463 Objective: Explain the relationship between electricity and magnetism. Key Terms: Electromagnetism: Relationship between electricity and magnetism. Electromagnetic Induction: process by which an electric current is produced by moving a wire in a magnetic field. Oersted’s Discovery Read this section. Answer the following question. USE COMPLETE SENTENCES. DESCRIBE: What did Hans Christian Oersted discover? Hans Christian Oersted discovered that an electric current produces a _______________ field. Electromagnetic Induction Read this section. Answer the following question. USE COMPLETE SENTENCES! DEFINE: What is electromagnetic induction? Electromagnetic induction is the process by which an electric _______________ is produced by moving a wire in a magnetic field. Standard(s): 5.6 TA: _____________ Independence Level: __________% Assistance, coaching, prompting: __________________________________________________ Word Bank for “Checking Concepts” induction electric current changing electricity CHECKING CONCEPTS 1. Oersted discovered that an ________________ ________________ caused a magnetic field. 2. An electric current is produced when a wire is exposed to a ____________________ magnetic field. 3. Michael Faraday discovered electromagnetic _______________________. 4. Electromagnetism is the relationship between ____________________ and magnetism. THINKING CRITICALLY ANSWER THE FOLLOWING QUESTIONS. USE COMPLETE SENTENCES. 5. DESCRIBE: What determines the direction of electric current in a wire when a magnet is moved around the wire? The direction of the current depends on the direction of the movement of the _______________. 6. EXPLAIN: What happens to a nearby compass when you disconnect a circuit? When you disconnect a circuit, the compass pointer will return to its _______________ position. (look in the “Oersted’s Discovery” section for this answer) 7. EXPLAIN: Why will an electric current not be produced in a wire that is exposed to a stationary magnetic field? Electromagnetic induction occurs only when a wire ________________ (moving or not moving) in a magnetic field. Page 2 of 2
