⚡ Electric Field Visualization Tool (3D)

Place positive and negative point charges anywhere in 3D space and watch real Coulomb-law field lines trace themselves outward with an even Fibonacci-sphere spread. Drag a green probe charge through the field to read its live magnitude, vector components and the force it exerts.

ControlsClick empty space to place a charge (positive/negative toggle, magnitude slider 1-20, placement-height slider for real depth); drag any charge or the green probe sphere to move it freely in 3D along the camera's view plane; a slider sets field-line density per charge (4-28, Fibonacci-sphere start directions); a probe-charge slider changes the test charge read by the live readout panel (|E|, Ex/Ey/Ez, resulting force); drag empty background to orbit the camera, scroll to zoom; Clear All resets the scene.
