Which statement best describes the effect of the magnet on the block of material next to it? S N OA. The magnet has magnetized the left side of the block. B. The magnet has magnetized the center of the block. O c. The magnet has magnetized the right side of the block.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
