Question

iron filings and bar magnets were placed on a sheet of paper. the following diagram shows the pattern made on the paper. at which location is the magnetic field the strongest? 1 2 3 4

Explanation:

Step1: Understand magnetic field strength

The magnetic field is strongest where the iron filings are most concentrated. Iron filings align along the magnetic field lines, and a higher density of filings indicates a stronger field.

Step2: Analyze each location

• Location 1: Far from the poles, fewer filings.
• Location 2: On the side of a pole, but not the closest interaction point.
• Location 3: Similar to location 2.
• Location 4: Between the \(S\) (south) and \(N\) (north) poles of adjacent magnets. The magnetic field lines are most concentrated here as it is the region of strongest interaction between the two magnets.

Answer:

4
