Hi All I have had an idea for a trick and need some help.
I am looking to make a small box, hinged at the front so you can open the front and I want to put 1 magnet in the base and I in the lid, so when you put any object into it it looks like it is floating. (object is allready magnetic or I have "made" it magnetic.)

can anyone help on what magnets I would need. is this even possible.

thanks in advance.

Not a science guy, but unless you're married to the magnet route, I can think of at least one way to accomplish the effect. A little flat black paint, a little IT...

I apologize if that's not the direction you want to go. Good luck.

I think you should find someone that has been working with PK for a while. They may be able to answer your question. The amount of power needed means you would need one of those $150 magnets. Chazpro Magic use to sell them, they are very heavy and thick, plus they are very dangerous if your hand gets caught between the forces.

I don't want to float heavy objects just stuff like sponge balls, and other small lightweight items

It seems you think a small light object can use a small magnet. I believe your thinking is in error. You will need a field large enough to encircle the object, otherwise it will just be thrown aside.

You may need several magnets of high strength. Just get out your charge card and start experimenting. It is that simple.

The cheap way would be to hang the thing with IT, and one of those classic picture lights in the front edge of the box to light up the interior.

Also remember you idea requires magnets to repel, thus the small object may need the opposite pole magnets at many places in the object you want to suspend.

You should do some magnet research on the science sites on the web. They will be more help then a magic site.

Are you thinking that if you have two magnets, top and bottom, that it's going to make something float?

For that to work, you would have to position the magnets exactly perfect for this to be achieved.
The magnets would also have to give off the exact same amount of magnification always.
Any minute fluctuation in the magnetism, be it strength or direction, and all will fail.

You can do stuff like this...

But ask anyone that has something like this and they will tell you how easy it is to get off kilter.
Plus, magnetism isn't an efficient form of energy. You will need great magnetism to achieve small feats.

That is a great find Randy, you can buy any of them and work on converting them to his box idea.

The Café members are so knowledgeable, it is a great bunch of guys and gals.

We solved another mystery! Hurray!!

Hi all, be aware that most of these devices require battery power. They use a fluctuating amount of magnetism with some feedback to keep the object centered.

The link and related video clips are pretty much the same as Randi's.
-------------
The bigger picture is, that a good guess by mostly any spectator watching any suspension or even levitation is that its an invisible wire, a string, or some sort of mirror or magnet. Bottom line, "if it looks like a duck, it probably is".
When PK factors came into place, the holy grail of suspension would be to have objects actually floating using our invisible friendly magnetic force. When you get done, it is a science project and not very magical.
---------------
Our job as magicians is to simulate floating thru magical techniques. Therefore, I would opt for black art when using a box.
If you have a known heavy object, then simulate it using light weight materials. Then float it with more conventional magical means. The problem with trying to do what you want, is getting there while being watched.
-----------------
Ther is a bank that is a mirror box that is a cool floating effect.

Bill and Randi, you're right on the money.

It is not simply two magnets. There is no way to simply get two magnets to cause levitation unless it was possibly in a vacuum and even then the balance could be thrown off and upset by virtually anything. All of the floating globe, pen, die or other objects all use the same technology. The battery in the base is rapidly fluctuating the electromagnet based on positioning feedback from the "floating" device itself.

If you are absolutely set on magnets then I would recommend getting one of the globe pieces or something else is in the approximate size for the box and build around it. Ultimately, I still think it's better using IT or other safer technology like the Harbin UFO display similar to the picture above.

Hi all thanks for all your great replies, it was only something that I had an idea for having looked into it a little deeper I think I have decided to leave this project for the moment, but if I come back to it in the future I think I will look into IT and other items and not magic.

once again thanks for all the help Smile
