Question

during a class demonstration, mrs. sabra poured iron filings over a bar magnet. the iron filings moved into a pattern around the bar magnet, as shown. at which locations are the magnetic forces the strongest? near c and d near c and b near a and b near a and d

Explanation:

In a bar magnet, the magnetic force is strongest at the poles (the ends of the magnet). Typically, the poles of a bar magnet are at its two ends (let's assume A and D are the ends/poles here, while B and C are closer to the middle). So the magnetic forces are strongest near the poles, which would be near A and D.

Answer:

near A and D
