- Low voltage is around the screen, creating a low-voltage AC field.
- The AC susceptibility of MTG-YBa_ 2 Cu_ 2.99 Li_0.01 O_ y sample was measured as a function of temperature with different dc field, ac field and frequency.
- Inductive proximity switches are designed for wear-free and non-contact detection of metal objects. For this they use a high-frequency electro-magnetic AC field that interacts with the target. ...
- The field artillery pounded away at the for tress.
- The crowd cheered as the teams entered the field.
- On the map the drains of each field are laid sown.
