Magnetic Fields

Definition

Magnetic fields refer to areas around magnets where they exert their influence. These fields can be used in various applications, including medical imaging techniques such as MRI.

Analogy

Imagine magnetic fields like invisible force fields surrounding magnets. Just like how these force fields attract metal objects nearby, magnetic fields in medical imaging machines help create detailed pictures of our body by interacting with atoms inside us.
