### Free Damped Forced and Maintained Oscillation

(1) Free oscillation (i) The oscillation of a particle with fundamental frequency under the influence of restoring force are defined as free oscil

### Harmonic and Non-harmonic Oscillation

Harmonic oscillation is the repetitive movement of an object or system about a fixed point or equilibrium position in response to a restoring force. It is a type of periodic motion that can be modeled mathematically as a sinusoidal function. Examples of harmonic oscillation include a pendulum swi

### Eddy Current and its Applications

Whenever a large conductor i.e. 2 dimension or 3 dimension conductor in placed in varying magnetic field an EMF is induced in it due to the find closed paths within concentric circular currents known as eddy currents. Eddy currents by nature are con

### Simple Pendulum

An ideal simple pendulum consists of a heavy point mass body suspended by a weightless, inextensible and perfectly flexible string from a rigid support about which it is free

### Hertz Experiment

Hertz produced and detected EM Waves experimentally. Experimental setup is as shown below.

### Some Important Definitions

(1) Time period : It is the least interval of time after which the periodic motion of a body repeats itself. S.I. units of time period is second.

### Spring Pendulum

A point mass suspended from a mass less spring or placed on a frictionless horizontal plane attached with spring (fig.) constitutes a linear harmonic spring pendulum

Test Details

The period of oscillation of a simple pendulum is given by T=2πlg  where l   is about 99 cm and is known to 1mm accu

Test Details

The least count of a stop watch is 1/5 sec.The time of 20 oscillations of a pendulum is measured to be 25 sec. The minimum percentage error in the measurement of time will be

Test Details

Two magnets are held together in a vibration magnetometer and are allowed to oscillate in the earth's magnetic field. With like poles together 12 oscillations per minute are made but for unlike poles together only 4 oscillations per minute are executed. The ratio of their magnetic moments

Test Details

A magnet is suspended in such a way that it oscillates in the horizontal plane. It makes 20 oscillations per minute at a place where dip angle is 30o and 15 oscillations per minute at a place where dip angle is 60o. The ratio of total earth's magnetic field at the two
