Hi, is this magnet always active and then the power demagnetizes it?

Hi, no, with 12v on the magnet is active and has force, When power is lost it demagnetize.

It's an electro magnet, power is applied to activate the magnet and must be removed to deactivate.

Yes, unfortunately it does pull some power even when turned off. I thought it didn't but my friend the electrical engineer convinced me otherwise.

It is a reed switch.... meaning it needs a magnetic field to change state. Power goes thru its contacts

No, this $8 magnet does not comes with a power switch as it is not an electromagnet. It also doesn't have regenerative braking or a hybrid engine that gets 50+mpg, nor can it be used as a floatation device in the event of a water landing. It does come with 2 covers over the magnet portion though, so it doesn't go "Magento" on you and impale itself with shrapnel. It is QUITE strong, though as with all magnets the rated force is in the optimal conditions (thick ferrous target and perpendicular force) - it will hold jeans up if you use i as a fridge magnet, but it will not hold your 95# kid in his jeans to the fridge.

It is normal, it's just telling you its receiving power. Mine does it too and nothing has gone wrong.

I have not noticed any magnetism, but I also do not keep my gun on it for long periods of time as yet. Generally it maybe on there for 2-4 hours 2-3 times a week sometimes longer. Next time I use the magnet I will see if there is any lingering magnetic effect.

I've never had a problem with demagnetized credit cards. Check out the myth busters episode on this.

The unit stays powered all the time. I not checked excessive heating (only a slight heating, that's normal).

Yes, I found mine doing that after a couple of weeks. Had to get a head cleaner demagnetizer. Worked fine after that.

It depends if your device is solid state or not. If it is solid state that means there are no moving parts so the magnets wont hurt anything. If your device is not solid state then you should power it completely off every time you store your laptop and move it. And if you do this properly, the magnets shouldnt have any affect on it. Also, the magnets are very small and not really what Id consider any threat to your device.

It gets a little warm but not hot at all. I have mine on all the time and it works fine. Had it connected to 12v and I could still pull it apart. I have it connected to 19v now and works awesome. Good little magnet, will be buying more.

Yep it is magnetizied...this set is great...I own a computer repair shop...this is the only set I have had to use.

It is supposed to. I thought that was what I ordered. Can't tell you because it hasn't been installed yet and won't be until the beginning of August. Will post again afterwards. Everyone else says 'no'. The video mentions the magnet, so I guess I assumed it was part of the unit.

Well, I checked and the magnet barely has any pull. I looked it up though and apparently this is still normal and doesn't mean it's not stainless steel. Here's a reliable source of info on it. http://www.scientificamerican.com/article/why-dont-magnets-work-on/

What a stupid question! Obviously the magnet that I purchased does not have a power switch. I consider that question insult my intelligence. No I am not happy with it no I'm not going to send it back because it's more hassle than it's worth

This is NOT a magnetic switch. I use this switch out the box for fractional hp at 120 or 220. For any application where a magnetic switch is used, this would serve to engage/disengage the magnetic switch.

The magnets are really strong. I've had mine about 4 months and it's fine so far.
