... representation of the definition of div and curl. They found that students who had visual cues available to them performed better with less mental effort and responded with greater confidence. They also found that the students who received visual cues tried harder to come to a coherent mental representation...

... in the structure is released that causes the curling/buckling. Temperature analysis for the Ohmic switch was performed on CoventorWare software. The direction of tip deflection changes from upwards to downwards for the transition from low to high-temperature, as shown in Fig. 6.15 . The cantilever tip deflection...

... undergraduate and graduate students' proficiency with different representations used in electricity and magnetism, both groups had difficulty identifying divergence and curl graphically, although the students were able to calculate them mathematically. These investigations suggest that advanced students may...

... = ∇ × A . Because Maxwell’s equation for the divergence of a magnetic field is ∇ ⋅ B = 0 , it can be written in terms of the curl of another EM field, i.e., Below, we will demonstrate very quickly how the MEs can instead be expressed in terms of two alternative fields, i.e., a vector field...

... λ L 2 ∂ J s ∂ t = E , where, λ L = m ∗ μ 0 n s ( e ∗ ) 2 . λ_L has the dimensions of length. Equation ( 4.3 ) is called the first London equation. Taking the curl of both sides of Eq. ( 4.3 ), (4.4) μ 0...

... that the Chern number is always an integer. Further, the Berry curvature, F is defined as the curl of the Berry connection, namely, (3.19) F = ∇ × A F is analogous to the magnetic field. The Chern number is defined as the surface integral of the Berry curvature over a surface...

..., ¹¹ called the curl, as in Fig. 7.4 . Fig. 7.3 Magnetic field lines. For every north pole there is a south pole. To understand Maxwell's third equation, we must go to the experiments that led to it. The first to recognize the connection between electricity and magnetism was the Danish...

.... 2.10 . The upper side of the wing has a lower pressure than the lower side. In the mid-span region, two-dimensional flow can already be expected. However, approaching the end tip region, the flow tends to curl up because of the imbalance in the net pressure level. This causes the flow near the tip...

...). Considering a source-free (ρ = J = 0) spatial uniform dielectric medium (∇ · E = 0), we apply curl operation on both sides of Eq. ( 2.4 ) and substitute Eq. ( 2.5 ) into it. Then, we obtain (2.20) u ( x , y , z ) = ∫ − ∞ ∞ d k x ∫ − ∞ ∞ d k...
