Unformatted text preview: These solutions are to this textbook but with some numbers slightly changed. These will give you the idea of how to solve the textbook style problems. 1) The magnetic field from free currents in the center of a wound coil B=0 N I where 0 is the permeability of free space. In the presence of material there is a component of B from free currents denoted H and a contribution from magnetization of the material M. To take this into account it is possible to write B= H where the contribution from magnetization is lumped into . So we solved for H earlier and should have written H=0 N I then B would be H times the relative permeability. can be very large for some magnetic materials such as Iron or Nickel. 2) 3) 4) 5) 6) The voltage and capacitance are different from the given problem but this is the solution. 7) The numbers are slightly different on these but this will give you the idea of how to solve them. 8) ...
