Double loop induction coil

A double loop induction coil is a type of electromagnetic device that is used to generate a magnetic field. It consists of two separate loops of wire that are wound around a core made of a magnetic material such as iron. The two loops are positioned in such a way that they are parallel to each other and close together, but not touching. When an alternating current is passed through the first loop, it creates a changing magnetic field that induces an electric current in the second loop. This process is known as electromagnetic induction. The induced current in the second loop can be used to power a device or to measure the strength of the magnetic field. Double loop induction coils are commonly used in a variety of applications, including inductive heating, wireless charging, and metal detection. They are also used in scientific research to study the properties of magnetic fields and to measure the electrical conductivity of materials.
