Magnetic Field Lines
Plotting field lines with compasses and bar magnets
This simulation allows you to explore magnetic field lines around bar magnets. Place compasses to visualize the field direction or click to trace complete field lines.
Magnetic Field Visualization
Observation:
Magnetic field lines emerge from the north pole and enter at the south pole. Compass needles align tangent to the field lines.
Magnetic Field Principles
1. Field Direction:
The direction of the magnetic field is defined as the direction a compass needle points (from north to south).
2. Field Strength:
Field lines are closer together where the field is stronger (near the poles).
3. Field Lines:
Field lines never cross and form continuous loops from north to south pole.
4. Compass Behavior:
Compass needles align with the field but don't affect it. Multiple compasses show field direction at different points.
