Question

Question: What conclusions are we to make about experiments with magnets,solenoids,electromagnets,electric field patterns created with iron filings ,suspended magnets,and electric field patterns made by a compass.What do all these factors determine about magnetism and magnets in the world,explain.

Answer 1

All these patterns are common in one sense that they make closed loops.

The iron filling near these objects form closed loops. The field patters made by compass also makes closed loops.

These closed loops give us idea that magnetic field lines form closed loops and as such its individual source and sink are not present.

A magnetic monopole as such does not exist as whenever a field line is generated it forms a closed loop making the total flux zero.

Hence, the important fact that we get from this idea is that magnetic poles always exist in pairs and single north or single south pole does not exist.
