Vedclass · Answer

(A) As the electron moves along the straight line,it creates a magnetic field. The magnetic field lines pass through the loop,creating a magnetic flux. According to Lenz's Law,the induced current will oppose the change in magnetic flux. As the electron approaches the loop,the magnetic flux through the loop increases. The direction of the magnetic field produced by the electron's motion (using the right-hand rule for a negative charge) results in a flux change that induces a current to oppose this increase. As the electron moves past the loop,the magnetic flux through the loop decreases. The induced current then changes direction to oppose this decrease. Therefore,the direction of the induced current is not constant; it changes as the electron moves,making it variable.

Near a circular loop of conducting wire as shown in the figure,an electron moves along a straight line. The direction of the induced current,if any,in the loop is
