MDCAT Physics MCQ #752

1. Question 1

   Q1. When a magnet is moved towards a coil, what is the direction of induced current according to Lenz's law?

   • A) Same as the direction of motion of the magnet
   • B) Opposite to the direction of motion of the magnet
   • C) Perpendicular to the direction of motion of the magnet
   • D) In the direction of the magnetic field

   Answer: Opposite to the direction of motion of the magnet

   Explanation: Lenz's law states that induced current opposes the change, so it flows opposite to the magnet's motion. Option A fails because it suggests the current aids the change.
