Learn to solve a complex electrodynamics problem involving magnetic fields generated by a magnetized cylinder using multiple analytical approaches. Work through Griffiths' Introduction to Electrodynamics Chapter 6, Problem 6.12, which examines an infinitely long cylinder with radius R carrying a "frozen-in" magnetization parallel to its axis, where M = ks*ẑ (k is constant, s is distance from axis) with no free current present. Master two distinct solution methods: first, locate all bound currents and calculate the magnetic field they produce using techniques from section 6.2, and second, apply Ampère's law to determine the H-field before finding B using equation 6.18. Explore the relationship between H-fields and bound current densities (J-bound) while comparing results from both analytical approaches. Access supplementary Python code demonstrating a third computational method for solving this problem, reinforcing theoretical concepts through practical programming implementation.
