Question

1. The rule for the force between two permanent magnets is:

2. Describe how the magnitude of the magnetic field is represented by magnetic field lines.

3. In the right hand rule for the magnetic force on a charged particle, we use the index finger, the middle finger, and the thumb. What is each digit used for?

4. In the formula for the magnetic force on a charged particle, what is the angle measured between?

5. The magnetic force vector is always __________ to both the magnetic field vector and the velocity vector.

Explanation / Answer

1. Like poles of two permanent magnets repel, while unlike poles attract. North pole will repel north pole but will attract south pole

2. Magnetic field lines are drawn closer for magnetic field of stronger magnitude. Magnetic field lines are drawn far apart for magnetic field of weaker magnitude

3. Index finger : Charge

Middle finger: magnetic field

Thumb: Force

4. Angle is measured between magnetic field vector and velocity vector

5. The magnetic force vector is always __perpendicular__ to both the magnetic field vector and the velocity vector.
