These sensors do not measure DC or static magnetic fields, for example from motionless magnets or the earth's magnetic field unless the sensor itself is vibrating or rotating. Hydrogen nuclei will align with and against this vector when the patient is at isocenter in the MR unit. The meter will react to changes caused by rotating the meter in the Earth's magnetic field, by a moving magnetic object, or by DC currents carried by wires . Manual for Measuring Occupational Electric and Magnetic Field Exposures NIOSH Publication No. Direct current produces a static or stationary magnetic field which would be 0 Hz. After the integration is carried out, we have a closed-form solution for part (a). Use to determine the strength of a magnet, its polarity, or whether an item has become magnetized. A magnetoquasistatic field is typically generated by low-frequency induction from a magnetic dipole or a current loop. The . The term EMF can describe electromagnetic fields with high or low frequencies. DC or "static" lines of magnetic flux naturally emanate from the earth and provide a compass with the ability to indicate "Magnetic North". This electromagnetic field meter is suitable for measuring both static/permanent magnet (DC) and alternating magnetic (AC) fields.
