Question
This question relates to the magnetic fields generated by a current in a long, straight wire. Express values to four significant figures Magnetising field strength What 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 wire carrying a constant current of 1.1 amps. A/m Magnetic flux density What is the corresponding magnetic flux density at P? || - T Iron A 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 magnetic permeability of the iron is 67.6, determine revised values for the fields at P: |H| A/m |B| T
