Consider a magnetic dipole with north and south poles, each of magnetic strength p/2, separated by a distance 2d. what is the magnitude of the magnetic field at a distancex from the middle of the dipole along the axis that connects the north and south poles? ci me: d 15 d tt lit b. consider now a solenoid with n loops, length 2a, radius r and resistance r. calculate the magnetic flux, p, of the magnetic field above through the area of the coil. in doing this, assume one-dimensional geometry in the (x- axis) only.
c. assume that the magnet above is attached to the end of a pendulum, such that x then, calculate the induced emf on the coil a = - x cos wt. dp dt dt dx
