The uses of electro magnetic waves in medicine?
Magnetic North.
Magnetic air cars uses air compression as the source for propusion. It is "magnetic" in the sense that a magnetic motor is used for the air compression.
it uses optical technology
The optical microscope uses a magnetic field to magnify images up to 1,000.000
That is called a magnetic compass.
There are three main types of magnetic compasses: the traditional liquid-filled compass that uses a magnetic needle, a digital compass that uses sensors to detect magnetic fields, and a gyrocompass that uses the Earth's rotation to determine direction. Each type has its own advantages and limitations, depending on the specific use case.
It uses a magnetic needle to point to the earth's magnetic North Pole. The only other type of compass used is a gyro-compass. This uses a wheel which rotates parallel with the earth's rotation.
MRI - Magnetic Resonance Imaging
Magnetic Resonance Imaging (MRI) is the diagnostic technique that uses a combination of radio waves and a strong magnetic field to produce detailed images of tissues and organs in the body.
uses a magnetic field; to view living cells
