The two magnetic poles are in close vicinity, which concentrates the field lines and creates a strong magnetic field. Magnetic fields of a horseshoe magnet visualized using iron filings. A horseshoe magnet is either a permanent magnet or an electromagnet made in the shape of a horseshoe (in other words, in a U-shape). The permanent kind has ...
What is a Capacitor? A capacitor is a two-terminal passive electrical component that can store electrical energy in an electric field.This effect of a capacitor is known as capacitance. Whilst some capacitance may exists between any two electrical conductors in a circuit, capacitors are components designed to add capacitance to a circuit.
for a magnet from NdFeB is relatively straightforward, but magnetizing a machined piece of NdFeB into a functioning magnet can be much more difficult. Magnetizing a piece of NdFeB requires a strong magnetic field in order to overcome the high coercivity of the material, and creating that field can be difficult and even dangerous.

Lines of force that are close together indicate a STRONG magnetic field. Lines of force that are farther apart indicate a WEAK magnetic field. Magnetic forces attract and repel like electric forces and when two lines of force are brought close together the interaction between the two magnetic fields causes one of two things to occur: 1.
A magnetic field (sometimes called B-field [1]) is a physical field that describes the magnetic influence on moving electric charges, electric currents, [2]: ch1 [3] and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. [2]: ch13 [4]: 278 A permanent magnet''s magnetic …

This tree is known as a Lichtenberg figure, named for the German physicist Georg Christof Lichtenberg (1742–1799), who was the first to study these patterns. The "branches" are created by the dielectric breakdown produced by a strong electric field. (Bert Hickman). A capacitor is a device used to store electrical charge and electrical ...
5.2: Plane Parallel Capacitor; 5.3: Coaxial Cylindrical Capacitor; 5.4: Concentric Spherical Capacitor; 5.5: Capacitors in Parallel For capacitors in parallel, the potential difference is the same across each, and the total charge is the sum of the charges on the individual capacitor. 5.6: Capacitors in Series
Upon integrating Equation (ref{5.19.2}), we obtain [Q=CV left ( 1-e^{-t/(RC)} right ).label{5.19.3}] Thus the charge on the capacitor asymptotically approaches its final value (CV), reaching 63% (1 -e-1) of the final value in time (RC) and half of the final value in time (RC ln 2 = 0.6931, RC).. The potential difference across the plates increases at …
