...nd inspect them for the presence of correlation by sending sound impulses as well as other digital transmissions at a standard distance (GSM, 3G, 4G , 5G DECT, etc.) The unit which you have selected is not a slightly improved version of the old device, but a completely new, revolutionarily changed sweeping tool..
3. Magnetic field signal detection,install the magnetic probe,turn on the power, press the strong magnetic detection switch, the purple indicator on the top of the magnetic prob after the light is on,enter the magnetic field signal detection standby,and the magnetic field induction probe is close to the magnetic field source, before the white LED of the the terminal LED light up and the buzzer alarm..
SPY DETECTOR: wide-band antenna (for ANT1 socket) Wider coverage, particularly at lower frequencies, has made it possible to increase the detection distance of a conventional VHF/UHF bug , while saving perfect sensitivity at the higher bands (GSM, Wi-Fi, Bluetooth, etc.).
Anti Spy Detector: (for ANT2 socket) when an affordable RF detector gets the microwave logperiodic directed antenna supplied in the standard set. 2-4 times longer distance to all sources above 2GHz (Wi-Fi 2.4GHz, Wi-Fi 5GHz, Bluetooth, Wi-Max, LTE High, etc.). The directionality ....

The rotating magnet provides the necessary tools to discover concepts involving Faraday's Law, magnetism, in addition to Lenz's Law.
Includes a 600 turn solenoid with two 4mm banana plug type terminals and an Alnico magnet on a rotating platform.
Apparatus measures 7.75" wide, 4.75" long and 3.5" tall.
Great for demonstrating how a time varying magnetic field produces an electromotive force, or how a wire's current can create a magnetic field and interact with another magnetic field.
