The figure below shows a cross section of the solenoid, with the magnetic field pointing out of the page. The electric field induced by the increasing magnetic field lies in the plane of the page. On the figure, indicate the direction of the induced electric field at the three labeled points Magnetic field due to solenoid using COMSOL The aim of simulation was optimization of high voltage head sizes and achieving smallest maximal electric field) (10) B = μ 0 μ r H + B r (11) F M = 4 3 π r p 3 χ i B μ 0 ∇ B where B is the magnetic flux density, μ 0 is the magnetic permeability of free space, μ r is the relative permeability, H is the magnetic field and. Search: Comsol A solenoid is a combination of closely wound loops of wire in the form of helix, and each loop of wire has its own magnetic field (magnetic moment or magnetic dipole moment). A large number of such loops allow you combine magnetic fields of each loop to create a greater magnetic field. The net magnetic field is the vector sum of the fields due to all the turns. Enamelled wires are used for winding so that turns are insulated from each other. Generally, the length of the solenoid is large as compared to the transverse dimension. For example, if the solenoid has circular turns, the length is large as compared to its radius.
