1. Electric current produces magnetic field, even if the current is very weak.
2. Ion current (very weak) which travels along the nerve cells in our body produces magnetic fields.
3. If we touch something, our nerves carry an electrical impulse to the muscles we need to use. This produces weak magnetic field.
4. Heart and brain are the two main organs where significant magnetic fields can be produced.
5. This forms the basis of obtaining images of heart and brain or images of different parts of the body.
6. This is done using a technique called Magnetic Resonance Imaging (MRI).
