Why are magnets influenced by DC power and not AC?

Hey dude, The charger is 14 volts, ur mags have the capacity to interupt this service cuz the charge is heavy and slow and ur mags have pull. The ac line has about 120 volts alternating at 60 hertz. To visualize this, Seperate your ac lines ( hot/cold), put a magnet 10x more powerful than your using now and place it between the seperated lines, you will see it vibrate at the hertz rate with a certain torque power very different than what you feel on the dc line.


These two links have several parts after them, watch them both ALL the way thru ( about 4 hours worth). I believe ur brain will be that much more screwed up and knowledgable on the subject, and by the way, slick video link, INCOGNEATO!!

I read somewhere that the magnetic force of the magnet is like a static DC power.

Maybe DC power has some kind of infinite frequency and resonates with DC and not with AC. I'm also discussing if DC power has some kind of frequency and not 0. The answer for now is... DC power has a NO MEASURABLE infinite frequency. So, that doesn't means that DC power = 0 Hz.

If you wish to learn more about the interaction of AC with PMs....

You're probably just seeing the effect of minor changes in the DC current caused by ripples in the DC voltage.

When you rectify AC (change it to DC) without power-smoothing capacitors you get a voltage that "ripples" between a peak and valley woltage. This is commonly ignored in battery chargers because for all practical purposes it has no effect on efficiency and smoothing the power would cost more due to additional parts. This ripple is also either exactly the same as the frequency of the AC (60Hz in North America) or double that frequency if your battery charger uses full-bridge rectification (More common).

The changing voltage in turn produces a changing current. The current flow is what creates and maintains the magnetic field. Fluctuations in flow = fluctuations in magnetic field.

Magnetic fields aren't a source of major loss in conductors because as the field contracts / collapses the energy used to create or expand them is returned to the conductor (Often all at once, which can be bad/damaging/dangerous and is why we use diodes, capacitors and other techniques to slow and otherwise reduce this effect).

Hope this helps with some of your questions.
