Electromagnetic induction (video) | Khan Academy
Due to a changing magnetic field we call them as induced currents or induced voltage. To differentiate it from the currents and the voltage we get from a battery. And this phenomena is …
What is Faraday's law? (article) | Khan Academy
What is electromagnetic induction? Electromagnetic induction is the process by which a current can be induced to flow due to a changing magnetic field. In our article on the magnetic force …
Magnetism and electromagnetism | AP®︎/College Physics 2
Explore the relationships between moving charges, the magnetic fields they generate, and the magnetic forces that act on other moving charges in those fields. Discover the natural …
Magnetic flux and Faraday's law (article) | Khan Academy
It turns out that how much magnetic field is passing through a conducting loop—or more specifically, how the amount of field passing through the loop is changing —is very important …
Diamagnetic anisotropy (video) | Proton NMR | Khan Academy
The induced magnetic field created by circulating pi electrons affects the effective magnetic field experienced by protons, influencing their chemical shift in NMR spectroscopy.
Lenz's law (video) | Khan Academy
When the magnetic flux through a conducting loop changes, current is induced in the loop. This current produces it's own magnetic field. Lenz's law tells us that the current flows in the …
Electric and magnetic fields (article) | Khan Academy
When a magnetic field changes over time (for example, due to the motion of a magnet or a current-carrying wire), it induces an electric field. This phenomenon is described by Faraday’s …
Faraday's Law Introduction (video) | Khan Academy
How a change in a magnetic field can affect or induce a current in a loop of wire. We're gonna be going from a change, change in, and actually we're gonna focus on magnetic flux.
Nuclear shielding (video) | Khan Academy
It details how a proton in a molecule, surrounded by circulating electron density, experiences a smaller effective magnetic field due to the induced magnetic field opposing the applied one.
Nuclear shielding (video) | Proton NMR | Khan Academy
It details how a proton in a molecule, surrounded by circulating electron density, experiences a smaller effective magnetic field due to the induced magnetic field opposing the applied one.
