(1) Free oscillation (i) The oscillation of a particle with fundamental frequency under the influence of restoring force are defined as free oscil
Harmonic oscillation is that oscillation which can be expressed in terms of single harmonic function (i.e. sine or cosine function). Example :
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
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 produced and detected EM Waves experimentally. Experimental setup is as shown below.
(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.
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

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
