Modern Medical Applications of Magnetism in 2026
One of the most exciting aspects of the 2026 curriculum is the emphasis on real-world applications. The magnetic effect of electric current is the backbone of modern diagnostic medicine.
1. MRI Technology
Magnetic Resonance Imaging (MRI) uses powerful electromagnets to align hydrogen protons in the human body. By applying radiofrequency currents, doctors can create detailed 3D images of soft tissues without using harmful ionizing radiation.
2. Magnetic Blood Flow Meters
Based on Faraday’s Law and the Lorentz force, these meters measure the velocity of blood flow. Since blood is a conducting fluid, moving it through a magnetic field induces a voltage that helps in monitoring cardiovascular health.
3. Transcranial Magnetic Stimulation (TMS)
In 2026, TMS is increasingly used to treat clinical depression and neurological disorders. It involves using an electromagnetic coil to create electric currents in specific areas of the brain.
