Magnetic fields have numerous practical applications in various fields of science and technology. Let's explore some of the key applications!

1. Electric Motors: Electric motors rely on the interaction between magnetic fields and electric currents to generate mechanical motion. The interaction of magnetic fields with the electric current in a coil causes the coil to rotate, enabling motors to power a wide range of devices, from kitchen appliances to industrial machinery.

2. Generators: Generators work on the principle of electromagnetic induction. When a conductor moves through a magnetic field, an electric current is induced. This phenomenon is utilized in generators to convert mechanical energy into electrical energy, providing power to our homes, businesses, and industries.

3. Magnetic Resonance Imaging (MRI): MRI machines use powerful magnetic fields and radio waves to generate detailed images of the human body. By manipulating the alignment of hydrogen nuclei in the body's tissues, the magnetic fields create signals that are detected and converted into images, assisting in medical diagnosis and treatment planning.
