Expert Answer:

Refer to your NCERT textbook for the solution or read the following excerpts of it below:
 
-An electric current always produces a magnetic field.
-Even weak ion currents that travel along the nerve cells in our body produce magnetic fields.
-When we touch something, our nerves carry an electric impulse to the muscles we need to use.
-This impulse produces a temporary magnetic field. These fields are very weak and are about one-billionth of the earth’s magnetic field.
-Two main organs in the human body where the magnetic field produced are significant, are the heart and the brain.
-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). Analysis of these images helps in medical diagnosis.
