Question

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

Answer 1

Answer:

The plane of the coil makes an angle of 45° with the magnetic field .... R moves in its plane with a uniform velocity v perpendicular to one of its sides

hope you get it...

Answer 2

Given that,

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

Suppose, A simple pendulum with charge bob is oscillating as shown in the figure. Time period of oscillation is T and angular amplitude is θ. If a uniform magnetic field perpendicular to the plane of oscillation is switched on, then

We know that,

The time period of oscillation is

$T=2\pi\sqrt{\dfrac{l}{g}}$

The magnetic force is

$F=q(v\times B)$

Magnetic force is always perpendicular to velocity.

So it will always act in radial direction which will change tension at different points. But, time period and amplitude will never changed.

Hence, The time period and amplitude of oscillation will not change
