Science Class 10 Board Exams: Key Concepts Quiz

The magnetic field exerts a force on the current-carrying conductor, causing it to move or experience a torque.

Light undergoes reflection when it bounces off a surface, following the law of reflection which states that the angle of incidence is equal to the angle of reflection.
