The fields emanating from various appliances may vary greatly. Field strengths depend on the amount of electrical current flowing through the appliance and appliance construction. Fields may be very strong close to the appliance, but they usually drop off rapidly with distance. At a distance of just 1 metre they will often be weaker than the other fields that may be present in the home. 

In general, it is often so that new appliances produce weaker fields than old appliances as the new appliances are often more compact and less energy-consuming than older ones. But this is not always the case. The amount of time in which and the distance at which we use the appliances may also differ greatly. 

Examples of magnetic fields produced by appliances:
