In Fig. 9 (a), the normalized amplitude of oscillation A ∗ for the cylinder undergoing non-rotating VIV is shown (which will be used as a basis to compare with), as well as the vorticity field at four selected values of the reduced velocity U ∗.As previously shown by Singh and Mittal (2005) and in Shiels et al. (2001), and found also here, the response is composed of two branches, the ...

5.8: Electric Dipoles - Physics LibreTexts

Figure (PageIndex{2}): A dipole is induced in a neutral atom by an external electric field. The induced dipole moment is aligned with the external field. An important fact here is that, just as for a rotated polar molecule, the result is that the dipole moment ends up aligned parallel to the external electric field.

Analytical Solution for MHD Flow of a Magnetic Fluid …

This finite value of induced magnetic field on the outer cylindrical wall has no doubt suggested that there exists an induced electric current within the solid outer cylinder. Because the outer cylinder is perfectly conductive, part of the electric current induced by the MHD flow will be able to bypass through the outer cylinder.

Magnetic Field from a Cylinder's Magnetization | David …

Currents are one known source for magnetic field, while time dependent electric fields are another. In this case, the magnetization of an object is known to be related to currents (bound currents to be precise) and there is no mention of any time dependence so it is sensible to proceed with the intention of solving for the magnetic field using currents as a source.

A liquid metal flow induced by a rotating magnetic field in a cylindrical container of finite height was investigated experimentally. It was demonstrated that the flow in a rotating magnetic field is similar to geophysical flows: the fluid rotates uniformly with depth and the Ekman layer exists at the container bottom. Near the vertical wall the flow is depicted in the form of a confined jet ...
