Question

2 if the magnet in source 1 is reversed so the red end points towards the camera, what pattern will the iron filings make on the glass?
a
b
c
d

Explanation:

Reversing a bar magnet flips its magnetic poles, but the overall magnetic field pattern (iron filings aligning to show lines from north to south pole) remains identical in shape, just with the direction of field lines reversed. The visual pattern of iron filings around the magnet will match the original pole-to-pole pattern.

Answer:

A. <The iron filing pattern showing curved lines from one end of the magnet to the other, matching the standard bar magnet field>
