The answer is yes. Permanent magnets can be used to perform task, that is : To perform as pistons in an eternal combustion engine. Magnetech Llc. John Pike @ johnamy_pike@Yahoo.com has developed a permanent magnet switching device, that enables magnets to perform in a reciprocating manner or operate a piston type engine, Engineering principles verified by prof. looking for assistance in final development of working protype.
Neodymium Magnets
Powerful electromagnets
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.
there are a lot of neodymium magnets coming from china lately.
Nothing, elctro magnets act just the same as permanent magnets
Electromagnets can be turned off and off
Electromagnet which uses electric current can be turned on and off.
no
Neodymium Magnets
Magnets.
Powerful electromagnets
Permenant magnets.
Electromagnets' magnetism can be manipulated. Electromagnets can be magnetised and demagnetised by passing electric current. Therefore they are used in motors- which works when the coil is magnetised by passing an electric current. It is also used for cranes.
You can turn electromagnets on and off.
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.
Electromagnets have an electric current running through them that enables there conductive power to be strengthened. However, a magnets full conductive power can never be "turned off/on".
Electromagnets are stronger and weigh far less than permanent magnets.
