Lenz's law: Induced current is always antiparallel to the motion that's causing it.
As a copper disk goes through a magnetic field in one direction, the magnetic field induces a current on the disc which is in such a direction as to create an electric field on the disc in the direction opposite its motion. Reeks of Newton doesn't it?
The electric force is therefore always slowing the disc down, otherwise known as damping.
What else can I help you with?
Why the oscillations of a copper disc in a magnetic field are are lightly damped?
The oscillations of a copper disc in a magnetic field are lightly damped because copper is a good conductor of electricity. As the disc cuts through the magnetic field, currents are induced that create a magnetic field opposing the motion, resulting in a damping effect. However, due to the high conductivity of copper, these currents quickly dissipate the energy, leading to lightly damped oscillations.
Is the ozone layer the same as Earth's magnetosphere?
The magnetic field diverts most positive charges of the solar wind to the south pole, and "scoops" more solar wind than Earth would otherwise receive. Much of these positive charges are hydrogen, the hydrogen oxidizes to water vapor, and water vapor both prevents one method of making ozone and accelerates the decay of ozone. So the magnetic field makes the south polar hole larger than the north polar hole, and serves to deplete ozone generally. Ozone is a polar molecule, and as such can be damped in oscillation / rotation by the Earth's magnetic field. So the magnetic field also serves to "cool" ozone down a bit.
During an earthquake where is the greatest motion felt on the surface?
Right at top of the epicenter, the greatest shaking felt. It also depend on the types of soil. If the soil is soft then the intensity is amplified and where the soil is hard the intensity is damped.
What is damping error in gyro compass?
This error is present in a compass which is damped in tilt. A compass damped in tilt always settles east of the meridian and above the horizon in NH, and vice-versa. Its magnitude depends on the observer's latitude, Sin( error ) α Tan( latitude ) At equator, the error is nil. The error is eastward in all northernly latitudes, and vice-versa. For the purpose of damping error, a latitude rider / adjuster is provided with the gyro compass which shifts the lubber line equal to the amount of error in the appropriate direction.
Is the planet earth's future in jeopordy because of human environmental interaction?
Yes. Our planet and us human are heading for danger. If the global warming continues the way it is has the last four to five years, then every living things will be out of ballance and matters will not follow their natural movement or actions. Starting the amount of rain we get in different parts of the world. Some will have sooo.... much rain like in India and Bangladesh and some will dry out like in some parts of Africa. In my life time, I have seen the Negative Impact of Green House immission , trees cut off with out any hasitation, dangerious chemichals damped into the sea or ocean and so on. On my part and my family, we will do our part. For every action there is a reaction. Yes, earths future is in jeopordy becaus of us human. My concern is the next 15 to 20 years there will be shortage of food and energy. Where there is too much rain, the crops will be distroyed and were there is draut there can be no harvet without water. Part of our problem is instead searching for the truth of reasoning and the truth of facts, (buddha), we tend to concentrate on other matters that our peace and resources are used for wars countries against another countries or tribes against another tribes. The matter is, we have One Earth that we live in. It is never too late to reverse the situation , It take commitment of every person on this earth. We also need to teach our children and grandchildren to respect nature and follow all the rules to preserve the earths inviromental health. No one but us can do it. So people, lets head for constraction instead for distruction.

What is the differences between damped and undamped oscillations?
damped vibrations:in damped vibrations the amplitude of the signal decreases with respect to timeundamped vibrationsin undamped vibrations the amplitude of the signal remains constant with respect to time
What is Posicast controller?
Posicast controller is a feed forward compensator which is used to reduce damped oscillations
Define damped oscillation?
Any oscillation in which the amplitude of the oscillating quantity decreases with time is referred as damped oscillation. Also known as damped vibration, http://www.answers.com/topic/damped-harmonic-motion
Is it possible to have damped oscillations when a system is at resonance?
Resonanceis aforcethat remains in a opposite position.It is also observed in physical media such as strings and columns of air. Any waves traveling along the medium will reflect back when they reach the end. It is possible to have damped oscillations when a system is at resonance.
Is a pogo stick a critically damped system?
No, a pogo stick is not a critically damped system. It typically exhibits underdamped behavior when bouncing, with oscillations that gradually decay over time due to damping effects. The damping in a pogo stick is usually not enough to make it critically damped.
What is mening of damped transducers?
Damped transducers are sensors or devices that have been designed to suppress or reduce unwanted oscillations or vibrations. This damping helps to improve the accuracy and stability of the transducer's measurements by minimizing the effects of external disturbances.
What is ment by damped oscillation?
Damped oscillation refers to a type of repetitive motion in which the amplitude of the oscillations decreases over time due to an external force or frictional effects. This results in the oscillations gradually coming to a stop. Examples include a swinging pendulum gradually losing its height or a vibrating guitar string eventually settling down.
What does decrement mean?
the act or process of decreasing; gradual reduction or Physics. the ratio of amplitudes of a damped harmonic motion in the course of two successive oscillations.
What are advantages of over damped response?
Some advantages of an overdamped response include faster settling time, reduced oscillations, and decreased sensitivity to variations in system parameters.
What is the difference between underdamped and overdamped oscillations?
Damped (or free) oscillation occurs when an object is set to vibrate at its natural frequency while forced oscillation involves the application of a force to keep an object in constant or repetitive motion.
Will damped oscillations occur for any values of b and k?
The answer will depend on what b and k are! And since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.
