My lesson

1. The pointer on a compass is the south (north) pole of a small magnet. If a compass were placed next to a bar magnet. In what direction would the pointer point?

To the right (left)

2. Positively charged particle in a uniform magnetic field moves in a circular path in the clockwise direction, parallel to the plane. In what direction do the magnetic field lines point

Out of the page

3. What should one do to maximize the magnitude of the magnetic force acting on a charged particle moving in a magnetic field

Maximize the strength of the magnetic field.

4. A charged particle is moving in a circular orbit in a magnetic field. If the strength of the magnetic field doubles, how does the radius of the particle's orbit change

It is halved

5. Which of the following is not a possible trajectory of a charged particle in a uniform magnetic field

l__>

6. A current-carrying wire in a magnetic field is subject to a magnetic force. If the current in the wire is double what happens to the magnetic force acting on the wire

It is doubled

7. Two wire carry current in opposite directions. What graph represents the magnetic force acting on each wire

Two wire carry current in opposite directions repel each other

8. Current carrying wire passes through a uniform magnetic field. At which point is the magnetic field the strongest

Relationship between the intensity of the field within a given formula r wire above, so as soon as the radius approaches zero, the force field will strive to infinity

9. Unit of a magnetic field

Tesla (=10,000 gauss)

10. The magnetic force on a charged particle is in what direction of its velocity

Perpendicular
