Electromagnetic Induction and Alternating Current
... If the self-inductance of an iron inductor increases from 0.01 mH to 10 mH on introducing the iron core into it, what is the relative permeability of the core material used? Twelve wires of equal length ‘l’ are connected to form a skeleton cube which moves with a velocity v perpendicular to the magn ...

... Recall that the charged parts of atoms are electrons and protons. When two protons come close together, they push one another apart. In other words, the protons repel each other. But if a proton and an electron come close together, they attract one another. Why do protons repel protons but attract e ...

... its ends into the box where the needle was, one on each side of the needle. A distinct and proper deflexion was now observed. A wire was then taken 10 times around the ring, and connected to a common quadrant electrometer. The deflexion was easy to see. It could also be just seen with only one turn ...

... • However, unlike an electrostatic charge, a magnet is always at least a dipole. • A dipole consists of two opposite poles separated by a distance. • Cutting a magnet in half will produce two dipoles. • The search for a magnetic monopole continues (i.e. particles consisting of single isolated pole). ...
