4. ### Physics Help! A 0.75 m-long solenoid consisting of 1200 turns is used to generate a magnetic field 0.30 T. How?

B = muo x n x i => i = B/ muo n where muo = 4pi x 10^-7; n = no. of turns per unit length; B = magnetic field induction i = 0.30/(4pix10^-7x1200/0.75) => i = 149.2A

10. ### Calculate the energy stored in the magnetic field if the permeability of the core is 500.?

Energy is .5 muo mur B H volume. If you know H and mur, you can easily compute the energy (assuming the core does not saturate). To determine the current use N=H length/currrent
