2 Bar Magnets & Compass Simulation

This simulation demonstrates the magnetic fields of two bar magnets and how a compass needle reacts to their magnetic forces. The simulation helps visualize the interaction between magnetic fields and the resulting forces on a compass needle placed in the vicinity of the magnets.

Activities

Observe the Magnetic Fields: Place the compass at different points around the magnets and observe how the compass needle aligns with the magnetic field lines. Try placing the compass at varying distances from the magnets.
Change Magnet Polarity: Reverse the polarity of one or both magnets and observe how the magnetic field lines and compass needle orientation change. Note the difference between like and unlike pole interactions.
Explore Magnetic Strength: Adjust the strength of the magnets and observe the effect on the compass needle. Compare how a stronger magnet influences the compass differently than a weaker one.
Investigate Magnetic Interference: Place the magnets in close proximity to each other and observe the interaction of their magnetic fields. Note how the compass needle responds to the combined fields of the two magnets.
Field Mapping: Use the compass to map the magnetic field lines around the magnets. Record the needle's direction at various points and draw the field lines based on your observations.
Effect of Distance: Move the compass gradually away from the magnets and observe how the magnetic field strength decreases with distance. Record the changes in needle orientation as the distance increases.
Question: Stacking bar magnets in series increases their magnetic field strength. True or false? Design an experimental setup to deduce and support your answer.
