Tesla per second (T/s)

A unit for how fast a magnetic field changes, used by safety standards to describe slew rate and Peak dB/dt. It captures the speed of the field change, which is what the body responds to, rather than how strong the field gets. Reports show this speed in Gauss per microsecond (G/µs) for engineering and in Tesla per second (T/s) for the regulatory frame the ICNIRP and IEC 60601-2-33 limits use, where 1 G/µs equals 100 T/s.
