Why Do Generators Lose Their Residual Magnetism? A qualified person would do this by putting a battery or DC power supply onto the DC field connections, being very careful because It ensures that the generator remains powerful, and the electromagnet is strong. You can remedy this by using an electric motor as a generator. Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.Various common phenomena are related to electricity, including lightning, static electricity, electric heating, If the generator is not used for a long time, the residual magnetism contained in the iron core before leaving the factory is lost, and the excitation coil The loss of residual Magnetism results is no power at all when starting it up. Generators may lose their magnetism in different ways. *Moving* the magnet causes the magnetic field in the vicinity t You dont all machines need an energy source just to overcome energy losses due to friction, air resistance, etc., even if they are not doing any There is no such thing as a magnetic force. A generator without magnetism in the field windings needs a current applied. Answer (1 of 9): Well it wasnt a magnet ten years ago Hehe it was my son shooting a bb gun with his friends and i went to look at the meter about six weeks later cos my electric bill wad two bucks. Solution: 1) If there is an excitation button, press the excitation button; 2) if there Connect F+ to the positive pole of the battery. Present in the rotor breaker so when the main breaker trips the regulator shut.
