What is the electric field?
Where there is electrical charge there is electrical field. We find it everywhere; it is usually present around electrical sockets, electrical distribution units, appliances, etc. Every electric conductor, which is under voltage, creates an electric field around it. This exists even when the electrical current is not running (even when the devices are switched off). It is enough that appliances are plugged in. Additional magnetic field is produced when the appliance is plugged in and electrical current flows through the device. Electric and magnetic fields are called low-frequency fields.
