when the iron filings are sprinkled on the glass, most are attracted to the magnets
where the magnetic field is
center poles balanced strongest

Explanation:

To solve this, we recall the properties of magnets. A magnet has poles (north and south), and the magnetic field is strongest at the poles. When iron filings are sprinkled, they are attracted most to the magnet's poles, where the magnetic field is strongest. The other options: "center" has a weaker magnetic field, "balanced" is not related to magnetic field strength or attraction of iron filings, and "strongest" describes the field at the poles. So the first blank is "poles" and the second is "strongest".

Answer:

First blank: poles
Second blank: strongest
