- Induction cooktop
Induction hobs work by driving a 20–100 kHz coil, producing intermediate-frequency magnetic fields that are strong at the hob edge and fall off steeply — and that most consumer gaussmeters cannot measure because their bandwidth stops at 2 kHz.

- Electric vehicle cabin (traction and charging)
EV cabins contain low-frequency magnetic fields from battery cables, traction motor and inverter, strongest in the footwell and over the pack, with a separate profile during fast charging.
