... electric field in the bulk which is an insulator when the charge density cannot slide. In the quantum Hall bilayer, depinning arises from the injected charge current which is applied only at the sample boundary. Thus, in this case, the critical current will depend on how the depinning “forces” are t ...

... current limiters (FCL) will solve the aforementioned problems by limiting the fault currents to an acceptable limit. Thus, the expensive equipments and upgrades would not be necessary. FCLs are installed in series with electric lines. During normal conditions, FCL impedance is very small, but when a ...

MFF 1a: Electric Charge and A Bar Magnet
... A permanent magnet is placed near a hanging negatively charged ball with the S pole of the magnet near the ball. The ball swings toward the magnet. What will happen if we place the magnet near the ball but with the N pole near the ball? Actually conduct the experiment and ask them to explain any dis ...

History of electromagnetic theory
For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
