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.
An iron wire has a cross-sectional area equal to 5.00×10-6m2. Carry out the following steps to determine the drift speed of the conduction electrons in the wire if it carries a cur
The temp gradient is similar to finding the slope of a line (when in two dimensions) Temp. Gradient= Change in Temp. value/Distance. dT/dx = (T2 - T1)/(X2 - X1)
Length contraction (relativity of length) is the length of a body moving with a relativistic velocity v = c relative to an observer is contracted by a factor in the direction of m
Voltage division: In a series circuit Ohm's law applies for each component. However, since the current is common to all components we have: V1 = IR1, V2 = IR2,
What is Atomic Models? The concept of atoms was first suggested by the ancient Greeks. The atom was supposed to be the smallest piece of matter. Then J. J. Thompson discovered th
When were foundations of quantum mechanics established? Foundations of quantum mechanics : The quantum mechanics foundations were established throughout the first half of th
In optics what is intended by the expression "constructive interference." Answer: This is factual for any kind of waves. Any time you have coherent waves of the same kind
Diamagnetism is a basic property of all matter, though it is generally very weak. It is due to the no cooperative behaviour of oepenrbiting electrons when exposed to an applied mag
A seat of EMF is in sequence with a resistor R1 and with a parallel combination of two other resistors R2 and R3. R2 is a changeable resistor whose resistance can be changed just b
In plotting a x y graph which axes is the dependent variable and which is an independent function. Ans) Normally or you can say conventionally we take the x axis as independen
