Can a color television be degaussed without a degauss coil?
Yes, but any such device would have to emulate the behaviour and have the power of an AC degaussing coil. There are two types of degaussing devices: AC (alternating current) and DC (direct current), which are commonly based on electromagnets. A magnetic field can be generated by passing an electric current through a coil – the electromagnet. The coil may have a hollow core, although a stronger magnetic field can be produced using a solid core made of a magnetic material, such as iron. An AC degaussing device uses alternating current to generate a magnetic field whose polarity alternates as the polarity of the input current alternates. The magnetic field is decreased over time, either by a control circuit or by slowly moving the degausser away from the device being degaussed. This helps to randomize any magnetic fields in materials in close proximity to the alternating magnetic field. A DC degaussing device uses direct current to produce a strong unidirectional magnetic field, which wil
