Answer 2

Oscillating metallic pendulum in a uniform magnetic field directed Perpendicular to the plane of oscillation slows down due to conduction current.

• In presence of uniform magnetic field perpendicular to motion of pendulum, conduction current sets up.
• Due to this conduction current, the pendulum experiences force = BIL
• Here B is the perpendicular magnetic field in region, I is the current induced and L is length of pendulum.
• The force acting is deaccelarating in nature which slows down the pendulum.
