Magnetic field in a coil
Web12 sep. 2024 · The magnetic field inside a toroidal coil (Equation 7.7.3) depends only on distance from the central axis and is proportional to winding density and current. Now let us consider what happens outside the coil. For this, we consider any path of integration ( C) that lies completely outside the coil. Web5 mrt. 2024 · The formula for the magnetic moment of a plane current-carrying coil is not restricted to rectangular coils, but holds equally for plane coils of any shape; for (see Figure ) any curve can be described in terms of an infinite number of infinitesimally small vertical and horizontal segments.
