EMF Detector: Magnetic Field

Detect electromagnetic fields with EMF meter, magnetometer and RF scanner

EMF Detector is an EMF (electromagnetic field) detector, magnetic field meter, and ghost-hunting EMF reader for Android. Read live EMF strength in microtesla (μT) or milligauss (mG) in seconds.

Whether you scan for paranormal activity, check Wi-Fi router radiation, or hunt hidden electrical wiring, EMF Detector turns your phone into a precision EMF scanner.

▶ MAIN FEATURES
• EMF detector — live electromagnetic field strength (μT, mG)
• Magnetic field meter — magnetic anomaly detection
• Ghost hunter mode — paranormal investigation EMF spikes
• RF scan — wireless device radiation
• Hidden wire finder — locate AC wiring inside walls
• Audio + vibration alert above threshold
• Sensor calibration — figure-8 motion tutorial
• Real-time EMF chart — last 60 seconds
• Dark mode for night investigations
• Works fully offline — no account, no ads block

▶ HOW TO USE
1. Open EMF Detector and move phone in figure-8 motion to calibrate
2. Move phone slowly near walls, devices, or suspect areas
3. Watch the gauge rise as EMF strength increases
4. Set audio alert threshold for hands-free scanning
