EMF detectors work with sensors to detect magnetic fields.

An EMF detector is a electro-magnetic-field detector. It is a small device that can fit into your pocket. EMF’s are the waves that are emitted by electronics and digital devices. (microwaves). This device can detect these waves, and if there is a dangerous amount where you are standing. this device can also be used to “detect ghosts” supposedly.
