Enclosed current
WebJul 15, 2024 · So net I enclosed is zero. I know that a magnetic field can be there even when net I enclosed is zero but that's when that angle between B (constant) and dl element is 90 degree but that's not the case here. For me, the net enclosed current will be zero regardless of wherever you choose loop- on toroid or outside. WebJul 8, 2024 · A current transformer is a transformer used to step down the line current to make it easier to measure. The total power in a transformer is the same on the primary and secondary sides. The only way to step down the current is by stepping up the voltage. Therefore, a current transformer is a modified step-up voltage transformer.

WebAug 6, 2024 · In other words, the answer should be that the current is enclosed by the surface BOUNDED by the Amperian loop, because of the surface integral. However, I notice that this definition of enclosed current …
WebJun 1, 2024 · 2. "Current density" (without any other adjectives) means "charge passing a plane per unit time, per unit area of the plane". "Surface current density" means "amount of charge in a thin sheet of current passing a given place, per unit time, per unit length across the wide dimension of the sheet of current". To be clear, let's consider a sheet ... WebOne of Maxwell's equations, Ampère's law, relates the curl of the magnetic field to the current density and is particularly useful for current distributions with high degrees of symmetry.

Consider a cylindrical wire with radius r and variable current density given by j is equal to j zero times 1 minus r over big R. And we’d like to determine the magnetic field of such a current inside and outside of this cylindrical wire.
