Digital Agenda October 22: Electromagnetism Cornell Notes

Standards:
MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.



Objectives

·     1.  Define electromagnetism, and explain how electromagnets create magnetic fields, and how they are used by watching a video, taking Cornell notes, and passing a post-quiz with a 3 or better.

1. Do Now: Magnetic Fields Pre-Quiz


Independent
1. Title Your Cornell Notes, "Electromagnetism Cornell Notes" and set them up. DUE MONDAY OCTOBER 28
(In order to leave, you must have ALL of the vocabulary done, and the questions answered up to #4. the rest is HW if you do not finish)

Questions
Review about regular magnets...:
1. Explain the features of a bar magnet, and draw it.
2. Describe what the magnetic field off of a bar magnet looks like. Draw it.
3. Explain how bar magnets attract and repel each other
Electromagnets...
4.  How are magnetic fields created with electricity?
5. Describe and draw what the magnetic fields around an electromagnet looks like.
6. Describe the 3 ways you can change the magnetic field of an electromagnet.
- distance
- current
- polarity
7. Why do YOU think coiling the wire in an electromagnet strengthens the magnetic field?
8. Describe how solenoids are made.
9. Describe the differences AND the similarities between a regular magnet and an electromagnet.
10. Explain the importance of electromagnets in motors.
