What is a Solenoidal? A solenoid is a device comprised of a coil of wire, the housing and a moveable plunger (armature). When an electrical current is introduced, a magnetic field forms around the coil which draws the plunger in. More simply, a solenoid converts electrical energy into mechanical work. What is solenoid and toroid?The solenoidality of the velocity field is valid on the theoretical level, for example on the differential form of governing equations. However, the divergence of the velocity field on an arbitrary numerical setup and process is not strictly zero; therefore, the solenoidal field cannot be strictly applied in practice.Feb 17, 2018 · 1 Answer. Certainly a solenoidal vector field is not always non-conservative; to take a simple example, any constant vector field is solenoidal.
