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.
