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.
Induction: The property of magnetism may be induced in a piece of material that does not normally have that characteristic. If a piece of soft iron is placed in the magnetic
Determine the axial force in the link AB of the lifting tongs which cross without touching. The weight of the crate is P44 kN and the width of the box is P45 mm The axial for

How do you calculate tensile strength? Tensile strength isn't really measured; it's calculated. It is explained as the point at which a sample of material fails when subjected
Pitch: It is the characteristics of a sound by which we can distinguish among a grave and shrill sound is known as pitch. It depends on frequency of the vibrating body and expr
Historical development of atomic models In olden days there was an idea that all matter is made of tiny indivisible particles. When Thomson discovered electron, this idea
