How to Draw Magnetic Field Patterns

Magnetism and electromagnetism • Magnetic fields and forces

Key concepts

What you'll likely be quizzed about

  • A bar magnet produces a magnetic field that extends around it, represented by field lines.
  • The direction of these lines points from the north pole to the south pole.
  • The density of the lines indicates the strength of the magnetic field; closer lines signify stronger fields.
  • For accurate representation, field lines should not intersect, as this would imply multiple field directions at a single point.

What signifies stronger magnetic fields in field lines?

Click to reveal answer

Stronger magnetic fields are represented by lines that are closer together.

Key notes

Important points to keep in mind

Field lines point from north to south in magnets.

Use the right-hand rule for current directions.

Closer field lines mean a stronger magnetic field.

Field lines do not intersect or cross each other.
