do magnets wear out over time from attracting things?

Question

I am going to attempt to build an unlimited source of free energy utilizing magnets. Do magnets wear out over time?

Answer 1

Strong and patented super magnets usually do not or never wear out and do not lose their magnetic charge so permanent use for a long period is guaranteed. Hard chromium coated magnets are known to be good.

There are also kinds of magnets like an ordinary ceramic magnets which lose their magnetic charge with time or when exposed to heat. Just be careful in choosing the kind of magnet itself.♥

Answer 2

At the moment, the relevant correlation for your project is given by Maxwell's Equations.

Basically, moving a conductor perpendicularly through a magnetic field produces a current in the conductor. Alternatively, wrapping a ferrous material with a wire and passing a current through it will create a magentic field.

ALL magnets exhibit hysteresis (which means they don't pass through the same points when magnetizing/demagnetizing). Eventually, this will mean your magnet reaches a point where it can no longer provide sufficient field strength to power your conductor.

As a magnet interacts with another (like polarity to like polarity), both will tend to weaken. If they interact in the opposite phase (like to unlike), they maintain their magnetism.

Depending on how you arrange things, you;re most likely going to have a finite life for your magnet portion ... assuming everything else in your system has infinite life.

Make sure you're checking for possible fault conditions, too ... a burst of energy in the wrong direction will be detrimental to magnet longevity!

Otherwise - best of luck putting your theory into practice.

Answer 3

Given time, the aligned crystalline fields will reorder themselves back to a random, a shorter time if they get hot.

This may take a couple of human lifetimes to accomplish, but I'm betting on the magnet "wearing" out before you break any conservation of energy laws:-)

Answer 4

It sounds like the ones you're asking about are ceramic. If you drop or jar them, they will loose some of their power as well. Each bump slightly aligns their magnetic molecules.

The world's strongest industrial magnets require electricity to increase their strength. They also need to be gas-cooled in some cases.

Answer 5

Magnets have an electric field and they are made up of protons nuetrons and electrons. Depending on the type of magnetic or electromagnetic object is where your answer is found. There are permanent magnets but there are also types and times that the magnet pull is lessened. You will have to determine what type of magnet to access whether there will be enough long term energy to power anything.

Answer 6

maximum cancers all human beings is very emotional, do no longer try saying recommend issues and undesirable stuff approximately him. Cancers at the instant are not that brave sufficient to attitude somebody, so why no longer supply it a shot? attempt to attitude him first, and as much as available, do no longer attempt to lie approximately your self and stuff. stay genuine :) stable success

Answer 7

sorry but you cant
+
they wear out over time
if u say no I can then try to pick you up without any support can u do that?

Answer 8

I believe that they can gradually lose some of their pull over time.
