Question

Some consumer groups urge pregnant women not to use electric blankets, in case there is a health risk from the magnetic fields from the approximately 1 A current in the heater wires. A) Estimate the magnetic field strength a fetus might experience, if it is approximately 10 cm from the current. What percentage of the earths magnetic field is this? B) it is becoming standard practice to make electric blankets with minimal external magnetic field. Each wire is paired with another wire that carries current in the opposite direction. How does this reduce the external magnetic field? -a-the two magnetic fields produced will be in the same direction so they will not affect the baby at all -b- the two magnetic fields produced will be perpendicular so the resultant vector will be very small -c- the two magnetic fields produced will be in opposite directions so they will mostly cancel eachother out Some consumer groups urge pregnant women not to use electric blankets, in case there is a health risk from the magnetic fields from the approximately 1 A current in the heater wires.
