Magnetism

Every AP Magnetism Problem to Date

Objectives

After studying the material of this chapter, the student should be able to:
1. Draw the magnetic field pattern produced by iron filings sprinkled on paper placed over different arrangements of bar magnets.
2. Determine the magnitude of the magnetic field produced by both a long straight current-carrying wire and a current loop. Use the right hand rule to determine the direction of the magnetic field produced by the current.
3. Explain what is meant by ferromagnetism, including the concept of domains and the *Curie temperature.
4. State the conventions adopted to represent the direction of a magnetic field, the current in a current-carrying wire and the direction of motion of a charged particle moving through a magnetic field.
5. Apply the right hand rule to determine the direction of the force on either a charged particle traveling through a magnetic field or a current-carrying wire placed in a magnetic field.
6. Determine the torque on a current loop arranged in a magnetic field and explain galvanometer movement.
7. Explain how a mass spectrograph can be used to determine the mass of an ion and how it can be used to separate isotopes of the same element.

*Every AP Magnetism Problem to Date





    Day 60
    Practice of RHR and its applications of right hand rule
    Online practice questions

    Day 61
    Forces between current carrying wire notes diagrams and discussion
    Yamato 1 magnetohydrodrive-> notes and discussion
    http://en.wikipedia.org/wiki/Magnetohydrodynamic_drive

    Day 62
    Induced EMF
    As it pertains to RHR. Wire sections and loops entering magnetic fields
    3 cases will be discussed and students will simplify analyze and apply RHR to and between case to explain the resulting current of a wire in a magnetic field.

    Day 63
    Quest on the direction and application of the RHR " Macarena effect quiz"
    Worlds simplistic motor student will set up and observe the operation of a simple motor consisting of a coil a battery and a magnet.
    Students will make observations
    Explain the purpose for each component and step in order to produce the desired effect
    Relate back to RHR

    Day 64
    Summarize key ideas to date-
    Discussion and Summary of key concepts of simple electric motor.
    Phase/ flux/ RHR will be explained in context. The ultimate goals is to provide the construct example for the functionality of emf to be used in future study of rail guns and emf.
    Notes mass spectrograph-
    AP2000 b7 student will analyze and explain both qualitatively and quantitatively the function of the device.

    5. #20 part E asks for the velocity of the projectile fired from a rail gun. My answer is almost exactly one-half of the correct answer and I can't find my error. If anyone else did this problem, or wouldn't mind doing it now, could you help?

    6. if you make a calculator error in one part of a problem and get a wrong answer, and you use that answer in another part of the question, do they penalize you twice?

    7. What is a curvature? It asks about it in number 2, and my partner and I can't figure it out.

      1. it is just asking how the radius of the circular path changes. It says curvature b/c it stops when it his the plate so its only a semi-circular path
