Biot-Savart law (J.B. Biot, F. Savart)
A law defines the contributions to a magnetic field through an electric current. This is analogous to Coulomb's law. Mathematically specking, it is dB = (mu0 I)/(4 pi r2) dl cross e where dl refer to the infinitesimal directed length of the electric current causing by the magnetic field, I refer to the current passing through that directed length, r refer to the distance from that directed length, & e refer to the unit vector directed from the test point to current-generating length.
Are fibers safe? Fiber optics are passive components, hence do not use power to generate light, like the case with lamps. When light conductors only carry light from one point
Illustrates the Electric Motors? An electric motor is basically the reverse of an electric generator. It is a machine which turns electrical energy - AC from the wall or dire
CENTRE OF GRAVITY: Consider a body as an accumulation of many small masses (molecules), all subject to gravitational attraction. The total weight, which is a force , is
Q. I n a Newton's ring experiment, the wavelength of the light used is 6 × 10 -5 cm and the difference of square of diameters of successive rings are 0.125 cm 3 . What will h
