Exercício Unesp 2026/2 - Um ímã em forma de barra está posicionado nas proximidades de uma espira

A bar magnet is positioned near a circular metal loop connected to an ammeter. This magnet can move along an XY axis that passes through the center of this loop and is perpendicular to its plane, as shown in the figure. Keeping the loop at rest, if the magnet oscillates along the XY axis, sometimes approaching and sometimes moving away from the circular loop, an induced electric current will circulate in the loop (A) only when the magnet approaches the loop. (B) only when the magnet moves away from the loop. (C) only when the magnet moves in the X direction. (D) when the magnet approaches or moves away from the loop. (E) only when the magnet moves in the Y direction.
