A mild steel closed magnetic circuit has a mean length of 75mm and a cross-sectional area of 320.2mm2.
A current of 0.40 a flows in a coil wound uniformly around the circuit and the flux produced is 200µWb.
If the relative permeability of the steel at this value of current is 400 find
(a) The reluctance of the material and
(b) The number of turns of the coil.
Q. What are secondary cells? Give an example? i) They are rechargeable. ii) The chemical reactions which take place in secondary cells are reversible. iii) The active mat
Que: What is an electric current? Answer: From Ohm's Law V = IR amid R being a constant one finds that I = V/R. therefore current is equal to voltage divided by resis
An electric dipole of dipole moment 20, X 10 -6 C.m is enclosed by a closed surface. What is the net flux coming out of the surface?

What is time? 1. This is the question that each true scientist dreads to be asked especially in a public setting by extremely inquisitive young learners. We have learned to ca
Poisson spot (S.D. Poisson) Originally Poisson predicted the existence of such spot, and utilized the prediction to revel how the wave theory of light have to be in error to g
When a string under tension is set into vibration, transverse harmonic rays propagate along its length. When the size of string is same, reflected rays will also exist. The operati
in a uniform electric field, the potential is 10v at the origin and 8v at each of the points (1,0,0),(0,1,0) and (0,0,1).Find the potential at the point (1,1,1).
Ferromagnetic materials get magnetic properties not only because their atoms owns a magnetic moment but also because the material consists of small regions called as magnetic domai
