EMF & Magnetic Detector
This app uses your device's magnetometer to detect magnetic and electromagnetic fields. It helps locate metal objects, hidden wires, pipes, and even wood studs behind walls. Get real-time readings and alerts to explore your surroundings.
- Detects magnetic and EMF fields
- Locates metal objects, wires, and pipes
- Finds hidden wood studs behind walls
- Real-time magnetic field intensity readings (μT & mG)
- Active detection beep alerts
- Automatic storage of time and measurements

Detect magnetic and EMF (electromagnetic) fields with your device. Find metal objects, locate nearby magnetic sources, and explore your surroundings. This app uses the magnetometer to measure the magnetic field when your device is placed near ferromagnetic metal objects like wires, pipes, coins, speakers, phones, metal screws, keys, computers, stereos, and much more! The Magnetic Detector is an application engineered to quantify the intensity of the magnetic field in close proximity, serving as an indicator of the presence of ferromagnetic materials. This tool capitalizes on the magnetic sensor integrated into mobile devices, delivering readings in units of μT (microteslas). Under standard environmental conditions, the Earth's magnetic field fluctuates around 49μT, equivalent to 490mG (milli gauss), with a conversion ratio of 1μT to 10mG. The proximity of metallic objects will induce a disturbance in the magnetic field, reflecting an increase in intensity readings. The Magnetic Detector is an effective tool for the identification and localization of metallic objects within a specified area, leveraging the intrinsic property of metals to generate detectable magnetic fields whose magnitude can be precisely measured with this instrument. Also you can discover magnetic fields and wood studs hidden under walls or plasterboard. As you move the device along the wall, the needle moves and when the limit is reached, it can be heard a warning beep. The features are: - Active detection beep when the above limit is reached. - The time and measure read is stored automatically. - A gauge indicating the magnitude of the magnetic field in uT and milliGauss. It could be used for construction workers & handymen: - to find where in the walls are hidden wires Students: - for educational purposes like school projects and experiments Tip: Shake for calibration Scientists, Teachers, Students, and Engineers, all use detector Meters for detecting magnetic fields of all types. Please note that Metal Detector is not a replacement for professional metal detector devices and it should be used for private/entertainment purposes only. If you have any issues to report or suggestions to make, please email the device you’re using and iOS version. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is ads: Physics Toolbox Sensor Suite at none against EMF & Magnetic Detector's shown. Physics Toolbox Sensor Suite also leads on update cadence (weekly vs every 2 months) and ratings volume (1.8K vs 439). EMF & Magnetic Detector's advantage is review sentiment (90% vs 80%) and device support (4 vs 2). On price, rating, in-app purchases and monetization model there is nothing between them.
