. The three quantities, c , the relative magnetic permeability m r , and the magnetic permeability are related as follows: m = m 0 m r m r = 1+x Magnetic materials are broadly classified as: diamagnetic, paramagnetic, and ferromagnetic. For diamagnetic materials c is negative an..

The dimensional formula of a physical quantity can be obtained by defining its relation with other physical quantities and then expressing these quantities in terms of mass [M], length [L] and time [..

..

X is the sum of 2 observed quantities a and b. X = a + b Maximum absolute error in X = Maximum absolute error in a + Maximum absolute error i..

Let D a and D b be absolute errors in measurement of quantities a and b and D X be maximum possible error in X. ..

Relative error in an is n times the relative error a It can be proved that maximum relative error in X, Also, maximum percentage error in X, Maximum percentage error in X = l times maximum percentage error in a + m times maximum percentage error in b + n times maximum percentage error in c..

Order of magnitude of a quantity is the power of 10 of the number that describes the quantity..

A unit of a quantity is the standard quantity used to measure a physical quantity..
