Colombian Lemur Studio Design fits shoes with mine detector

The video explains how a radio transmitter works in detecting mines. It describes the process of generating an electromagnetic field using a coil, which is disrupted when the wearer approaches a mine containing metal parts. This disruption triggers the transmitter to send a signal to a wristwatch, which then sounds an alarm and displays the mine's location on its screen.

What is the primary function of the coil in the radio transmitter?

• To produce an electromagnetic field

• To store electrical energy

• To generate sound waves

• To amplify signals

What happens when the wearer is within 2 meters of a mine?

• The wristwatch displays a countdown

• The transmitter stops working

• The electromagnetic field is strengthened

• The electromagnetic field is disrupted

How does the wristwatch alert the wearer about the mine?

• By vibrating

• By sending a text message

• By changing color

• By sounding an alarm and displaying the location

What role does the transmitter play when the magnetic field is disrupted?

• It sends a signal to the wristwatch

• It powers off

• It records the disruption

• It changes frequency

What information is displayed on the wristwatch screen?

• The time of day

• The battery level

• The location of the mine

• The weather forecast
