Magnetic Moment

The magnetic moment is defined as the alignment of a magnet and its strength when the magnet is creating a magnetic field. There are number of examples of the magnetic moment, few are a current carrying conductor in the form of coil, elements at microscopic levels like electrons and many more.

Question

The magnetic circuit shown in Figure P13.11 has
two parallel paths. Find the flux and flux density in
each leg of the magnetic circuit. Neglect fringing at the
air gaps and any leakage fields. N = 1,000 turns,
i = 0.2A, l_g1 = 0.02 cm, and l_g2 = 0.04 cm. Assume
the reluctance of the magnetic core to be
negligible.

I need helpo with this. I need step by step solutions for this and I cant figure it out. Wire to be used in buildings and homes in the United States is standardized according to the AWGsystem (American Wire Gauge). Wires are assigned a gauge number according to their diameter.The scale ranges from gauge 0000 to gauge 36 in 39 steps. The equation for the wire gauge interms of the wire diameter in millimeters is the picture. (a) What is the equation for the diameter in millimeters in terms of the wire gauge N?(b) You have two wires, one that has five times the diameter of the other. By how much do thewire gauges differ for the two wires? (Give your answer to the nearest integer.)
