NEW Topics covered on Final Exam

NOTE: These are the new topics that will be covered on the part (roughly 2/3) of the Final Exam that is like a fourth mid-term test.
There will also be review questions on topics that are detailed in another web page.

Chapter 28

1. B-fields near magnets
2. Lorentz force ( F = q v×B )
3. Three-vector Right-Hand-Rule
4. No work by magnetic field
5. Circular motion in magnetic field: radius, period, and frequency
6. Helical motion in magnetic field
7. "Crossed fields" (E and B), velocity filters
8. Hall effect
9. Force on straight current-carrying wire in magnetic field ( F = i L×B )
10. Net force on non-straight current-carrying wire in magnetic field (L from beginning to end)
11. Magnetic dipole moment of a current-carrying loop or coil ( μ=NiA )
12. Curled-straight Right-Hand-Rule
13. Torque on magnetic dipole in magnetic field ( τ = μ×B )
14. Potential energy of a magnetic dipole in a magnetic field ( U= –μ•B )

Chapter 29

1. Biot-Savart law: Magnetic field due to a small segment of current; integration
2. Magnetic field due to a straight wire segment (both along its axis and perpendicularly away from its end)
3. Magnetic field near an infinite straight wire
4. Magnetic field due to a wire arc (at center)
5. Magnetic field due to combinations of shapes: superposition (of vectors!)
6. Magnetic field due to a magnetic dipole
7. Force between current carrying wires
8. Ampere's Law; "current enclosed"
9. Magnetic field in a wire, with various current densities
10. Ampere's law for concentric pipe configurations
11. Magnetic field due to a solenoid

Chapter 30

1. Qualitative current induction
2. EMF
3. magnetic flux
4. Lenz's law
5. Faraday's law: induction of current
6. Faraday's law with flux change due to changing B field
7. Faraday's law with flux change due to changing Area (moving parts cause "motional EMF")
8. Faraday's law with changing angles
