“…From the perspective of concentration measurement application, target electrolytes are able to take the place of the insulating layer. These types of applications have already been investigated in the electromagnetic analysis of seawater [22] and magnetorheological fluids [23]. The results of the above investigations are extended in this research work to improve the sensitivity of solute concentration measurement in electrolytic solutions with the influence of magnetic field.…”

“…A few of the research works focus on the technologies like tomography [28], Electrochemical Impedance Spectroscopy [29], chronoamperometry [30], while some others focus on input signal models [31]. From a physical perspective, the impact of electromagnetic waves on conventional electrode models has not been explored for nonmagnetic electrolytes [23]. Therefore, this study investigates the effect of the magnetic field on the electrode model with an improved electrical equivalent model that explains its impact by accommodating the models explored in [32].…”

Voltammetric sensor models are widely used in electrolytic applications in industry and the laboratory. Research in these domains is enriched with data analytics tools and electrode design, which need to be revised to improve the sensitivity near the Nernst limit. Therefore, an intense demand exists for enhancing the sensitivity of conventional voltammetric sensor models with minimum alteration of design parameters. This research article focuses on the possible impact of a magnetic field in a conventional voltammetric sensor for electrolytic concentration measurement. The experimental results show a 45% increase in sensitivity with a 3%–43% increment in signal attenuation due to the magnetic field. Apart from analysing the impact of a magnetic field, this research also investigates sensors with different electrode materials and input excitation. Among different electrode materials, a sensor with Iron-Niobium is found to have maximum electrolytic sensitivity of 15.78 V mol−1 l−1 while measuring the electrolytic concentration of oxalic acid in the range of 0.001–0.01 mol l−1. Similarly, the proposed voltammetric sensor with Iron-Niobium electrodes is implemented to measure the concentration of other electrolytes with 10–130 V mol−1 l−1 sensitivity to enhance applicability. A modified electrical equivalent model with an additional inductive component is also proposed in this research work that explains the waveform dip followed by a peak overshoot due to the influence of the magnetic field. The proposed electrical equivalent model of electrode–electrolyte interface is compatible with a conventional model, which is confirmed based on the experimental observations and mathematical analysis.

“…Xuan et al [15] studied the shear properties of MRF under non-uniform magnetic fields, and the results showed that nonuniform magnetic fields could significantly increase the MRF shear stress. Zheng et al [16] studied the permeability of MRF in variable non-uniform magnetic fields and showed that the magnetic field state significantly affects the permeability. It can be seen that the particle chain will be affected by the magnetic field gradient force in the non-uniform magnetic field, which will change its motion state and thus influence the performance of MRF compression and shear.…”

Magnetorheological fluid (MRF) is a widely used intelligent material that can quickly respond to external magnetic fields. To effectively control the motion of the particle chain inside the MRF, this paper combines the traveling magnetic field (TMF) with the MRF to study the movement of the single particle chain in the MRF under the action of the TMF for the first time and discusses the influence of the moving velocity of the TMF and the magnetic induction intensity on the motion displacement and the velocity of the single particle chain, determines the adjustable range of the single particle chain motion parameters, and builds an experimental platform to observe the motion of the single particle chain. The results show that under the action of the TMF, the single particle chain makes a variable velocity reciprocating motion, and the displacement amplitude of the single particle chain is inversely proportional to the moving velocity of the TMF but directly proportional to the magnetic induction intensity of the TMF. The single particle chain velocity amplitude is only proportional to the magnetic induction intensity and is unrelated to the moving velocity of the TMF. This study shows that adjusting the TMF parameters can effectively control the displacement and velocity of single particle chain motion. This study provides a compelling new method to control the motion pattern of single particle chains in MRF.
