write about visualizing magnetic field

Answer:
Hey❤️
The easiest way is to take a small compass and move it around within a magnetic field. The direction the compass points is tangent to the curve of the magnetic field line at any location. A nice tool for this, using a small bar magnet instead of a compass is the following I got from Arbor Scientific
Answer:
Summary
Students take the concept of etch-a-sketch a step further. Using iron filings, they begin visualizing magnetic field lines. To do so, they use a compass to read the direction of the magnet's magnetic field. Then, as they rotate the filings about the magnet, they observe the behavior of iron filings near the magnet. Finally, students study the behavior of iron filings suspended in mineral oil, which displays the magnetic field in three dimensions.
