## What is Magnetic Detector?

Use Your Device to Detect Magnetic Fields. With this app you can detect wood studs hidden under walls, drywall, plasterboard, or stucco.

Magnetic Detector uses your device's compass (magnetometer) sensor to precisely detect metal studs, nails, screws, and other metal fasteners embedded in all wooden wall studs.

This app operates in a similar manner to other hand-held stud detector tools: as you move the device along the wall, the needle will move and a beep can be heard.

Magnetic Detector is an application which detects the presence of metal nearby by measuring the magnetic field value. This tool uses the magnetic sensor built-in your mobile device and shows magnetic field level in μT (microtesla). The magnetic field level (EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG. If any metal is near, the value of magnetic field will increase.

Metal Detector allows to identify any metal object in area, because all metals generate magnetic field which strength can be measured with this tool.

Features:
- Automatic sensor that measures the magnetic field in uT.
- Active detection beep.
- You can save the time when the measure is taken.

### 5/5 — It works!

*2023-07-11, version 1.2*

I was skeptical but it will locate studs and find metal.

### 5/5 — A app that works

*2023-03-16, version 1.2*

Really good app finally found one to test my meteors and the results are satisfactory

### 5/5 — Love it

*2023-01-27, version 1.2*

Love this app

### 5/5 — 不错

*2023-01-25*

### 5/5 — Works well

*2022-11-17*

Found this for looking for electronics and it works well!

### 5/5 — Surprised… and pleasantly so!

*2022-11-14*

I just stumbled across this app this morning, while searching for one with a similar name, and thought I’d give it a whirl. If the readings it’s consistently giving me on my i-devices and MacBook are accurate, then maybe it’s time to go back to using a regular quartz Seiko watch and using a Bluetooth keyboard to put some more space between my body and the left front corner of my MacBook! Also of note were the readings from my old (wired) Apple earbuds and wireless airpods…

### 5/5 — Better than the read

*2022-11-05*

Works much better than the others I’ve tried…the results will depend on what type of device you are using.

## Frequently asked questions about Magnetic Detector

### What does the Magnetic Detector app do?

This app uses your device's built-in magnetometer sensor to detect magnetic fields. It can help you locate hidden metal objects, such as wood studs, nails, screws, and other metal fasteners embedded in walls made of drywall, plasterboard, or stucco.

### How does the app detect metal?

The app measures the magnetic field strength around your device. All metals generate a magnetic field, and when you bring your device near metal objects, the magnetic field value will increase, indicating their presence. The app provides a visual needle and an active beep for detection.

### Is the Magnetic Detector app free to use?

The application is free to download and use. However, it offers in-app purchases, suggesting that some features or advanced functionalities might require a purchase.

### What devices is the Magnetic Detector app compatible with?

The app relies on the device's compass (magnetometer) sensor. Therefore, it is compatible with any mobile device that has a functional magnetometer sensor. The description does not specify operating system limitations.

### Can this app find coins?

Yes, the app can detect the presence of metal nearby by measuring the magnetic field. Since coins are made of metal and generate a magnetic field, this tool can help identify them if they are close enough to be detected by your device's sensor.
