Voorbeeldzinnen

1. Magnetic flux
2. Magnetic flux density
3. Magnetic flux density, B (μT)
4. Of these quantities, magnetic flux density, contact current, electric and magnetic field strengths and power density can be measured directly.
5. Designed to operate with a magnetic field slew rate exceeding 1 × 106 magnetic flux quanta per second;
6. the projectile risk from ferromagnetic objects in static magnetic fields with a magnetic flux density greater than 3 mT;
7. Having a temperature coefficient less (smaller) than 0,1 magnetic flux quantum/K.
8. Magnetic field strength is a vector quantity (H), which, together with the magnetic flux density, specifies a magnetic field at any point in space.
9. In free space and in biological materials, magnetic flux density and magnetic field strength can be interchanged using the equivalence 1 A/m = 4π 10—7 T.
10. Magnetic field strength is a vector quantity (H), which, together with the magnetic flux density, specifies a magnetic field at any point in space. It is expressed in amperes per metre (A/m).
11. Magnetic flux density is a vector quantity (B), resulting in a force that acts on moving charges, expressed in teslas (T).
12. For frequencies up to 100 kHz and for pulsed magnetic fields, the maximum current density associated with the pulses can be calculated from the rise/fall times and the maximum rate of change of magnetic flux density.
13. ‘action values’: the magnitude of directly measurable parameters, provided in terms of electric field strength (E), magnetic field strength (H), magnetic flux density (B) and power density (S), at which one or more of the specified measures in this Directive must be undertaken.
14. Examples of such conditions are: a grounded individual exposed to RF in the low MHz range and individuals exposed in the near field of an antenna. Of these quantities, magnetic flux density, contact current, electric and magnetic field strengths and power density can be measured directly.
15. ‘Electrical’: for the purposes of subheadings 72091610, 72091710, 72091810, 72092610, 72092710, 72092810 and 72112320, flat-rolled products which under a current at 50 Hz and a magnetic flux of 1 T have a watt-loss per kilogram, calculated by the Epstein method, of:
