Question

Oscillating metallic pendulum in a uniform magnetic field directed Perpendicular to the plane of oscillation

Answer 1

Answer:

If a uniform magnetic field perpendicular to the plane of oscillation is switched on, then. Solution : Mangetic force is always perpendicular to velocity. So it will always act in radial direction which will change tension at differenct points.

Answer 2

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

Explanation:

• When a uniform magnetic field is directed perpendicular to the direction of motion of pendulum, conduction current is produced. This conduction current produced affects the oscillation of the pendulum in the following way.

• The force experienced by the pendulum is calculated by = BIL

        B-PERPENDICULAR MAGNETIC FIELD ,

         I-CURRENT

         L- LENGTH OF PENDULUM

• The force acting on the pendulum is decreasing in nature which slows down the pendulum as time increases. Hence the conduction current produced during the experiment decreases the acceleration of the pendulum.
