Lesson 1441 of 1524

Magnetic Forces and Fields

Magnets have two types of magnetic poles, called the north magnetic pole and the south magnetic pole.

Practice this chapter

Magnets have two types of magnetic poles, called the north magnetic pole and the south magnetic pole. North magnetic poles are those that are attracted toward Earth’s geographic North Pole

Charges moving across a magnetic field experience a force determined by F → = q v → × B → . The force is perpendicular to the plane formed by v → and B →

magnetic force — force applied to a charged particle moving through a magnetic field. force — perpendicular to the plane formed by v → and B →. north magnetic pole — currently where a compass points to north, near the geographic North Pole; this is the effective south pole of a bar magnet but has flipped between the effective north and south…. south magnetic pole — currently where a compass points to the south, near the geographic South Pole; this is the effective north pole of a bar magnet but has flipped just like the north magnetic pole.

Worked example

What does “magnetic force” mean in Magnetic Forces and Fields?

  1. 1Use the wording this chapter gives for magnetic force.
  2. 2The book says: force applied to a charged particle moving through a magnetic field.
  3. 3Do not use the meaning of force. That term means perpendicular to the plane formed by v → and B →.

Result: force applied to a charged particle moving through a magnetic field

Why. That is the meaning this chapter gives for magnetic force.

Do not swap magnetic force and force. magnetic force means force applied to a charged particle moving through a magnetic field. force means perpendicular to the plane formed by v → and B →.
