This question relates to the magnetic fields generated by a current in a long, straight wire.Express values to four significant figuresMagnetising field strengthWhat is the magnitude of the magnetizing field strength at a point, P, a perpendicular distance 1.2 mm from the centre of a long straight narrow wirecarrying a constant current of 1.1 amps.A/mMagnetic flux densityWhat is the corresponding magnetic flux density at P?|| -TIronA piece of iron is placed so that the point at which you have evaluated the magnitudes of the magnetic fields lies within it. If the relative magneticpermeability of the iron is 67.6, determine revised values for the fields at P:|H|A/m|B|T

Given: Perpendicular distance d=1.2mm=1.2*10-3m. Current I=1.1A

Answered: Magnetising field strength
