Detecting the body's magnetic fields with a low-power Ramsey-based magnetometer

Our bodies generate extremely weak magnetic fields as electric currents flow through the heart, brain and other tissues. These signals are used in magnetocardiography and magnetoencephalography to assess heart function and brain activity, respectively. These fields can be detecte This story matters for Science & Discovery readers tracking student. Reported by phys.org. Read the full original at the source link below.
