How come magnets aren't a source of unlimited energy when the force between them is constant?
When standing in a bus-queue with a constant force between my feet and the ground there is no obvious source of energy, unlimited or finite.
If I fall onto my neighbours shopping bag, crushing her eggs, some energy is supplied but it is limited. As soon as my body is flat on the ground there is no more energy to be had.
If two magnets are held an inch apart, north opposite south and south opposite north, there will be an attractive force. There is potential energy here, and if the magnets are allowed to come together work will be done, energy supplied. This is not unlimited energy; it stops being available as soon as the magnets jam up against each other.
Of course, you can recharge that energy by pulling the magnets apart, but then your muscles will have supplied the energy.
The motto of physics, and of the entire universe, is TANSTAAFL.
There ain't no such thing as a free lunch.

How is bond energy related to your separation of the magnets?
Bond energy refers to the amount of energy required to break a bond between atoms or molecules. In the context of magnets, the strength of the magnetic bond between the magnets affects how much energy is needed to separate them. A higher bond energy indicates a stronger attraction between the magnets, requiring more force to pull them apart, whereas lower bond energy means they can be separated more easily. Thus, the bond energy directly influences the difficulty of separating the magnets.
Is magnetism consider a form of energy?
yes magnet is energy, surprisingly. magnets have at least one north pole and south pole, which make magnets have energy. Magnets provide energy. When you have two magnets and they are pushing against each other, that is how magnets provide energy. Magnets are better for the enviornment, because magnets are pollution-free.
What are some examples of magnetic energy transfer?
Some examples of magnetic energy transfer include the use of magnetic fields in transformers to transfer electrical energy, magnetic resonance imaging (MRI) to transfer energy for imaging purposes, and magnetic levitation trains that use magnetic fields to transfer energy for propulsion.
What happens to kinetic energy and potential energy in a closed system?
In a closed system, the total energy (kinetic + potential) remains constant, following the principle of conservation of energy. As kinetic energy increases, potential energy decreases, and vice versa. This continuous exchange between kinetic and potential energy allows the system to maintain a constant total energy.
What relationship exists between height and potential energy if mass is held constant?
The relationship between height and potential energy is directly proportional when mass is held constant. As an object is raised to a higher height, its potential energy increases. This relationship is given by the equation: potential energy = mass x gravity x height.
What does Magnetic potential energy is dependent on?
Magnetic potential energy is dependent on the magnetic field strength, the distance between the magnets, and the orientation of the magnets with respect to each other.
What do magnets never do?
Magnets never run out of energy.
How do you get unlimited energy in Mafia Wars MySpace?
UNLIMITED Energy is not possible...
When you push repelling magnets together is there potential energy in the system If so where If not what happens to the energy used to push the magnets together?
Yes, when you push repelling magnets together, there is potential energy stored in the system due to the work done to compress the magnetic field. This potential energy is stored in the magnetic field surrounding the magnets. When you release the magnets, this stored energy is converted back to kinetic energy as the magnets repel each other.
What is planck constant?
Planck's constant describes the ratio between the energy of an electromagnetic wave and the frequency of that wave.

What is the relationship between constant pressure enthalpy and the changes in a system's energy content during a process?
Constant pressure enthalpy is a measure of the energy content of a system at a constant pressure. During a process, changes in the system's energy content are reflected in the enthalpy changes. The relationship between constant pressure enthalpy and changes in energy content is that they are directly related - as the enthalpy changes, so does the energy content of the system.
What is the relationship between the energy of a photon (E), its frequency (v), and Planck's constant (h)?
The relationship between the energy of a photon (E), its frequency (v), and Planck's constant (h) is given by the equation E h v. This equation shows that the energy of a photon is directly proportional to its frequency, with Planck's constant serving as the proportionality constant.
What are some examples of magnetic energy transfer?

What does boundless mean?
Boundless can mean unlimited. You have boundless energy means you have unlimited ammounts of energy.
Is two magnets separated kinetic or potential energy?
neither. they separate because of magnetic fields. its not kinetic. its not potential. If you hold them together.. the "push" of them trying to get apart is storing some potential energy.. kind of like a spring. I guess you'd call it elastic potential energy because i dont know if there is such a thing as magnetic potential energy... hmm..
How can a magnets perpetual motion generator be designed to generate continuous energy?
A magnet's perpetual motion generator can be designed to generate continuous energy by utilizing the magnetic field to create a constant rotation of the generator's components. This rotation can then be harnessed to produce electricity through a system of coils and magnets, allowing for a continuous supply of energy without the need for external power sources.
