Transcribed Image Text:A. Answer briefly
1. What must be the magnetic polarity of the end of a bar magnet that is attracted to the
north end of another bar magnet?
2.
Above the end of a vertical bar magnet, a compass points downward. What is the
magnetic polarity of that end?
3. At a specific location, how is the spacing between magnetic field lines related to the field
strength?
4. What must be the direction of the velocity of a charged particle if it experiences no force
while in a magnetic field?
5. What is the orientation between a charged particle's velocity and the magnetic field if
the particle is to experience the maximum magnetic force?
6. If a charged particle moves perpendicularly to a uniform magnetic field, what is the
shape of its trajectory and how does that shape depend on the particle's speed?
Transcribed Image Text:B. Magnetic Field Lines
Sketch the field line for the following two cases:
7. Two bar magnets with adjacent north poles
8. Two parallel bar magnets with opposite poles
9.
The diagram above depicts two bar magnets suspended by string. If "N" labels one end of the magnet as magnetic north,
then determine the magnetic pole labeled with "?".
10. Right Hand Rule
If electrons in a conductor are moving from west to east, in which direction would the magnetic field be produced when looked from the east end?
