Question

1. magnets are surrounded by a magnetic field. it is the magnetic field that creates the force (a push or a pull) on other magnets or magnetic materials in the field. magnetic fields are invisible. scientists represent the invisible magnetic field by drawing magnetic field lines (top drawing). these lines point from the north pole to the south pole outside of the magnet. the magnetic field is strongest (or the magnet has the strongest pull or push on other magnetic material) where these lines are bunched closely together and weakest where they are spaced farther apart. a common way to visualize magnetic field lines is to sprinkle many tiny iron filings near a magnet (bottom picture). the iron filings line up with the magnetic field lines. at which point is the magnetic field of a magnet the strongest, at the poles or farther away from the poles? use a description of what you see in the diagram and/or picture as evidence.

Explanation:

The magnetic field strength relates to field line density. The text states field lines are closer at stronger regions, and diagrams show lines bunched at poles (farther apart elsewhere). Iron filings also align densely at poles, matching the description of stronger fields where lines are close.

Answer:

The magnetic field of a magnet is the strongest at the poles.
Evidence: The text says magnetic fields are stronger where field lines are bunched closely together; diagrams show field lines densely packed at the poles (north and south) and spaced farther apart away from the poles.
Reasoning: Dense field line spacing indicates stronger magnetic force, so the poles (where lines are closest) have the strongest field.
