Place + and - charges and watch real electric fields, field lines and contours.
Joker Glitz
Joker Glitz is a hands-on electrostatic field studio that runs entirely on your device 📱. Drop positive and negative point charges onto a plane, drag ✋ them with your finger, and watch 👀 the electric field respond instantly ⚡ - real physics, computed live, with nothing to log in to and no connection required.
Everything you see 👀 is solved from the actual equations, not a canned animation 🎬. The field is built by superposition of every charge, field lines are traced step by step along the field direction, equipotential contours are extracted from the sampled potential, and a released test charge is integrated under the Coulomb force so you can watch its path curve through the field.
FIELD STUDIO
- Place and drag ✋ any number 🔢 of + and - charges on the plane.
- See 👀 field lines, equipotential contours, the vector field, and an optional grid - toggle each layer on or off.
- Switch between Lines, Contours, Vectors and a Combined view.
- Tap 👆 a charge to change its polarity or strength, or delete it.
- Drop a test charge and watch 👀 its trajectory trace out under the force of the field.
- A live readout shows the charge count and net charge as you work.
SCENARIO LIBRARY 📚
- Load classic configurations with a tap 👆: dipole, quadrupole, like pair, line of three, screened pair, single charge, grid of four and a triangle ring.
- Every preset draws a real field preview, computed from its own charges.
FIELD PROBE
- Drag ✋ a probe point anywhere to read the field strength and potential at that spot, with a live field-vector arrow.
- Drag ✋ a sample line and read its potential profile V(s) as a smooth trace, so you can see 👀 exactly where the potential rises, crosses zero and falls.
MEASUREMENT LOG 📝
- Save 💾 any configuration and reload it later.
- Attach a photo 📸 of your real-world setup - a lab bench, a demo rig, a sketch - straight from the camera 📷 or your gallery 🖼️, so a saved measurement documents the apparatus it came from.
SETTINGS
- Tune the solver to your device 📱: grid resolution, field-line density, contour count and trace length.
- Choose a colour map 🗺️ (Mono, Warm or Signed), toggle the grid, snap-to-grid, field animation 🎬 and haptics.
Joker Glitz is fully offline 📴. There are no accounts, no network features and no data collection 📚 for any of its tools 🛠️. It is a qualitative visualizer built for exploring and building intuition about electrostatics - the magnitudes are shown in illustrative units, not calibrated laboratory readings.
Whether you are learning how fields and potentials behave, teaching the idea 💡 of a dipole, or just enjoy watching field lines reshape as you move a charge, Joker Glitz turns the invisible electric field into something you can place, drag ✋ and probe with your own hands.
