I want to make a project with an arduino, that uses magnets to enable and disable the attraction between them. I was wondering if it is possible to make the magnets attract themselves without using energy and by sending a pulse you disable this attraction, instead making them stick together by using 12v and turning this off by taking off the power.
Any comments will be greatly appreciated.
Some materials can be magnetized by a coil conducting electrical current, and demagnetized by the same coil.
It takes quite a bit of electrical power to magnetize a substantial object.
Not an Arduino project.

No. Physics doesn't work like that.

A permanent magnet will attract and stick to a ferromagnetic bar without using electricity. A sufficiently strong electromagnetic coil around the bar can overcome that attraction when a pulse of power is applied. It is not clear what the Arduino has to do with any of that.
