Classical simple harmonic oscillators consider a 1d, classical, simple harmonic oscillator with miltonian h (a) calculate the classical partition function z. (b) calculate the helmholtz free energy and energy

50 inches should be the resultant vector

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
