"An electro-magnetically driven loudspeaker comprises of a moving coil. The moving coil is used to convert electrical signals into acoustic energy. The...
can anyone help with me understanding the physical mechanisms that determine the current that flows through a MOVING coil immersed in a magnetic field when a fluctuating voltage is applied across the coil?
Also I need to find a Differential Equation that describes the behaviour of the current...
