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.
Electric current may be expressed in which one of the following units? a) coulombs/volt b) joules/coulomb c) coulombs/second d)

Can you differentiate between half wave plate and full wave plate?
Over the universe differ in magnitude from place to place. It is get that many places have the similar value of magnetic components. The lines are illustrated connecting all places
Chemical changes during: Discharging: The current will flow from positive to negative plate in the external circuit. As current now enters by negative plate, the negative
