Perfecting the performance of nerve implants

Researchers are extending their understanding of the effectiveness of electrical fields that are increasingly being used in implants to stimulate and repair damaged nerves. Effective nerve stimulation is the key to helping ...

Real-time MRI captures wrists in motion

In a proof-of-concept study published in The British Journal of Radiology, UC Davis clinicians and researchers have shown that a new, low-field 0.55T MRI (magnetic resonance imaging) system can create clear videos of moving ...


Engineered material can reconnect severed nerves

Researchers have long recognized the therapeutic potential of using magnetoelectrics—materials that can turn magnetic fields into electric fields—to stimulate neural tissue in a minimally invasive way and help treat neurological ...

Magnetic field

Magnetic fields surround magnetic materials and electric currents and are detected by the force they exert on other magnetic materials and moving electric charges. The magnetic field, at a given point, is specified by both a direction and a magnitude (or strength); as such it is a vector field.

In special relativity, the electric field and magnetic field are two interrelated aspects of a single object, called the electromagnetic field. A pure electric field in one reference frame is observed as a combination of both an electric field and a magnetic field in a moving reference frame.
