Consider a magnetic dipole with north and south polos, each of magnetic strength p/s separated by a distance 2d. what is the magnitude of the magnetic field at a distance x from middle of the dipole along the axis that connects the north and south poles ne: des b. consider now a solenoid with n loops, length 2a, radius r and resistance r. calculate the magnetic flux, , of the magnetic field above through the area of the coil. in doing this, assume one-dimensional geometry in the (x-axis) only
