Magnetic Resonance Imaging (MRI): The magnetic field inside the body forms the basis of obtaining the images of different body parts. This is done using a technique called Magnetic Resonance Imaging (MRI). But, these fields are very weak and are about one-billionth of the earth's magnetic field. So, statement 1 is NOT correct. MRI is not based on tracing heat patterns. So, statement 2 is NOT correct.
