Magnetic Core Parameters and Defaults
2.22 Coreless Coil
This component is a conceptual model that you can use as a building block to create a wide
variety of inductive and magnetic circuit models. Typically, you would use the coreless coil
together with the magnetic core to build up systems that mock the behavior of linear and
nonlinear magnetic components. It takes as input a current and produces a voltage. The output
voltage behaves like a magnetomotive force in a magnetic circuit, that is, when the coreless
coil is connected to the magnetic core or some other resistive device, a current flows.
