  • Magnet Effects on Phone

    Does magnet have any effect on cellphones?

    According to a source (an old friend doing E.E. research actually) which I found very reliable, if the magnet is powerful, then yes, some metal parts inside might be magnetized and this might alter the performance. Maybe the speaker or mic would malfunction or they might work better. But then again, since the magnetic field is not changing, no current will be induced, and for a nicely shielded circuitry inside the phone, a relatively small magnet would unlikely have any real effect on it. In fact, minuscule magnets are already part of speakers and mics, right?

    What do you think? Any scientific/engineering proof or calculation?

      I think it’s because engineers are more business-minded while physicists are more research-minded. Well, not all.

      Anyway, during muktamar last year, one brother complained that his hotel card was demagnetized twice by his cellphone.

      the cellphone itself is radiating some induced magnetic field (from variable current?) demagnetizing the card, woosh. sooner or later, the long term average is our brainwave being cooked by talking too long on the phone :D

      believe me, engineers are doing the research for businesses. they take whatever academics and scientists (including physicists) know into a project, attach time scale and money to the business objective, and improve it over time. sounds like entrepreneurs to me.

      engineer: business with scientific knowledge, or scientist with business knowledge.

      my 2.5 cents worth. you decide which is which. :)

      Zach says: As far as I know magnets shouldn’t affect a cell phone at all. If the magnet is stationary relative to the cell phone then it would definitely not affect it. If it was moving then it could create some EMI (electro-magnetic interference), but most cell phones operate above 900Mhz and I don’t think anyone is getting a magnet to vibrate anywhere near 900 million times per second.

      Jet: I use a VERY STRONG magnet to hold my celphone to the dashboard in my car. The plastic body of phones are usually coated or painted with metallic coatings which create a “faraday cage” that will cancel out RF and magnetic interference. That being said, if an electronic device is NOT protected in this manner it can be affected by magnetic fields. Put a magnet against your TV screen and see!

      hm, anymore input?

    It is always impossible to tell the level of impact you have on others. One smile. The moment you help someone. The moment you deny someone. The results you never planned. The outcome you never meant. Things you do or say now may have their way of coming around again after a year, 2 years, or 10 years later. Who knows?

    Have you ever wished that you could go back a couple of years and re-live every thing again? Just to improve things around? But then the results would either remain the same or turn entirely bizarre that you wish you hadn’t go back in the first place?

    You can never go back in the first place anyway. That’s the rule. While you’re making your way through, pick up as many lessons as you can and learn from others mistakes as well. Then look ahead. As far as you can and as deep as you can. Imagine if you are about to do something now, is there anything that you would’ve done differently so that in the future you will not have the desire to go back again?

    Even better, is there anything that you would’ve done differently today if you know that you are going to die tomorrow?

    It is a super simulation come to think of it. By our own Creator. We are all being tried, given the circumstance and options at hand. We cannot deny or run away or hide. There is only one way and there is no other way but to deal with it.

    As for me, I have made countless mistakes in the past. And I can’t emphasize enough how sorry I am for all those. But I have also learned that being apologetically sorry don’t cut it. We all have to reduce the same error we are doing now to zero and start making up for it. The first step in the right direction is to acknowledge the errors and begin mitigating. Another first step in the right direction is also this – we have to acknowledge the fact that we actually do make mistakes and sometimes, if not most of the time, we are totally oblivious to it.

    Step back and think again. You might not be able to change the past, but you have the power to change what you are doing now. Stop what you think is hurting people. Stop what you think is harmful for your own self (working on it). Stop what you think is pushing other people away (ongoing). Stop what you think is hurting your loved ones.

    Take care and good bye now. Not sure if we’d see each other again, but do say hi if you bump into me tomorrow. :) I don’t bite.

      manusia nie, kdg2 dia sedar kesilapan dia and dia berazam utk tidak mengulangi kesilapan yg sama.tp tanpa disedari (atau mungkin dia sedar), dia tetap membuat kesilapan yg sama berulang kali.

      sometimes, dia pernah lihat org lain membuat satu kesilapan and mungkin dia berazam utk tidak menjadi seperti org tu tp apabila dia berada di ‘tempat’ org tu beberapa tahun kemudian, dia melakukan kesilapan yg sama.

      knp eh?sedangkan dia telah belajar dari pengalaman org lain.

      if i knew the answer, i would’ve written it. :-) nampaknya kene refer to wiser folks. maybe that’s the reason we need the significant other? supaya bolih tegur and peringatkan yg mana lupa. :) lgpun, kalau belajar dr pengalaman sendiri, kesannya lebih kuat berbanding tgk pengalaman org

      liza, saya tumpang gelak ye? thihi! ive accepted the fact the world i live in is a twisted one that ive lost interest to be hurt over trivial things.

      life is too short to keep doing mistakes in order to learn frm them. thats why we learn from others’ as well. but worst case scenario – doing ur own mistakes, then acknowledging it but still do nothing about it.

      and i am saying this generally.

      yerp intan..life is so short.kalau kita nak belajar semuanya dr pengalaman sendiri, kena ambil masa beribu tahun. itulah pentingnya org sekeliling kita. mcm zid kata, memberi peringatan.

      to zid..hope u’ll find the answer u’ve been serching for one day.

      for someone absent-minded like me, erm, who repeated mistakes many times, i think there’s a reason why i learned things the hard way. so they stick. and they stick good.

      thanks. i hope i will to. hopefully its not too late by the time i found it. heheh.
