magnetic field visualize

A magnetic field is an invisible area around a magnet where magnetic forces act. It can be visualized using iron filings, which align along the field lines, revealing the pattern of magnetic influence. These lines emerge from the magnet's north pole and curve around to its south pole, indicating the direction and strength of the magnetic force. The closer the lines are, the stronger the magnetic pull. Think of it as an invisible force pattern that shapes how the magnet interacts with objects nearby, guiding magnetic materials and affecting electrical devices in proximity.
