Carving knife

Belongs to:
Kitchenware and household appliances
Synonyms:
Electric carving knife
Description:

For an electric carving knife, the alternating electric and magnetic fields at the fundamental frequency of 50 Hz resp. 60 Hz are caused by the motor for the translational back-and-forth movement of the blade.

Frequency ranges:
  • 50–60 Hz
Type of field:
electric and magnetic

Measurements (acc. to literature)

Measurand Value Feature Remarks
magnetic flux density 0.02 µT (mean, measured) - average value of 5 different knives at a distance of 100 cm; measurement bandwidth: 40 - 800 Hz [1]
magnetic flux density 0.12 µT (mean, measured) - average value of 5 different knives at a distance of 50 cm; measurement bandwidth: 40 - 800 Hz [1]
magnetic flux density 27.03 µT (mean, measured) - average value of 5 different knives at a distance of 5 cm; measurement bandwidth: 40 - 800 Hz [1]
