The following terms find importance in magnetism . Explain them a. Magnetic permeability (mu) b. Magnetic intensity (H) c. Intensity of magnetisation (I) d. Magnetic susceptibility (X_m) |

Answer» Solution :a. Magnetic permeability is the ratio of magnetic INDUCTION to magnestising field STRENGTH Permeability , `mu=B/H` b. It is the field produced by the Amperian current. If n is the number of turns of a SOLENOID and I - the current through it, then H = nI. It is the magnetic field magnetises the medium and is called magnetic intensity. c. Intensity of magnetisation is DEFINED as the magnetic moment per unit volume. `I=M/V,M` - magnetic moment , V - volume d. The ratio of intensity of magnetisation to the MAGNETISING field strength is defined as magnetic susceptibility (X) `X=I/H` |
