What are magnetic alternating fields?
Magnetic alternating fields are fields generated by changing electrical currents. They differ from static magnetic fields in that they periodically change their direction and strength. These alternating magnetic fields occur in many everyday applications, such as when using alternating current in household appliances, transformers, or power lines.
How are magnetic alternating fields generated?
Magnetic alternating fields are created when an alternating current flows through a conductor. Since the current constantly changes, the magnetic field surrounding the current also changes. These fields are proportional in intensity to the current strength and change direction according to the frequency of the alternating current. In practice, this means that a field with a frequency of 50 Hz or 60 Hz (common power grid frequencies) changes its direction 50 or 60 times per second.
Where can magnetic alternating fields be found?
Magnetic alternating fields occur wherever alternating current flows. They can be found in household appliances, industrial plants, high-voltage power lines, and everyday electrical devices. Particularly strong magnetic alternating fields occur near transformers, electric motors, and induction coils. Wireless charging technologies also use magnetic alternating fields to transfer energy.
Effects of magnetic alternating fields
Magnetic alternating fields can affect electronic devices and measuring instruments as they can cause disturbances. In certain cases, especially with strong exposure, they may also have health effects, which is why limits have been set for the strength of such fields. However, in everyday life, the fields are generally relatively weak and do not pose a health risk.
