Magnetic intensity formula class 12
WebWhen a plate of magnetic material of size 10 cm × 0.5 cm × 0.2 cm (length, breath, and thickness respectively) is located in a magnetizing field of 0.5 × 10 4 A/m -1, then a magnetic moment of 0.5 Am 2 is induced in it. Find the magnetic induction in the plate. VIEW SOLUTION Exercises Q 4 Page 264 Web3 mei 2024 · The intensity of magnetization is defined as the magnetic dipole moment per unit volume. It is denoted by I. Mathematically, i.e. I =$\frac {M} {V}$ Or, I =$\frac {m\times 2l} {A\times 2l}$ ($\because $M = m×2 l & V = A×2 l, 2l is the effective length of a bar magnet.) $\therefore I=\frac {m} {A}$
