Item details:

It is desired to achieve a time-varying magnetic flux density in the air gap of the magnetic circuit of Fig. 1.38 of the form

Bg = Bo + B1 sin ?t

where B0 = 0.5 T and Bl =0.25 T. The dc field B0 is to be created by a neodimium-iron-boron magnet, whereas the time-varying field is to be created by a time-varying current. For Ag = 6 cm2, g = 0.4 cm, and N = 200 turns, find:

a. the magnet length d and the magnet area Am that will achieve the desired dc air-gap flux density and minimize the magnet volume.

b. the minimum and maximum values of the time-varying current required to achieve the desired time-varying air-gap flux density. Will this current vary sinusoidally in time?
