How do you magnetize metal?
You can rub a magnet with the metal in single direction for a bunch of times (the more the better), and that will magnetize it to some degree, but it's not permanent and will demagnetize if it is hit hard with something.
A simple harmonic oscillator of amplitude A has a total energy E. Determine (a) the kinetic energy and (b) the potential energy when the position is one-third the amplitude. (c) Fo
