I notice that Kreis makes a magnetic half dollar that they claim to be the most powerful made. Can anybody verify this claim? Are they really more powerful than the Johnson brand which can be had for half the price of a Kreis?

The Kreis magnetic coins are of varying strengths from moderate to very strong. I think Johnson makes a one-size fits all model of this. It's good but I'm sure that the Kreis options on this are legit based upon what you need to do what you want with these sorts of coins.

Do you have experience with the coin they deem "very strong"? And if you do, is it actually more powerful than the Johnson or other economical brands?
I need one to use with a magnetic detector and I want the most powerful made, but I don't want to pay $50.00 for a coin that is not any more powerful than the cheaper versions. |

Rowdymagi5,
I would recommend that you contact KREIS and ask them for the "strength grade" of their coins. Good luck with asking Johnson Products about any specifics for their coins, as from past experience, I can say that they're tight-lipped about such. All neodymium magnets (as used in magnetic coins) are objectively graded for magnetic strength. Thus, you can compare apples-to-apples and not apples-to-oranges. Example grades: MN35, N38, N42, N38SH...what does it all mean? Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number following the 'N'), the stronger the magnet. The highest grade of neodymium magnets currently available is N52. If the highest grade avaiable is N52, then you need to ask KREIS how large is the inner magnet within the coin (the diameter)? Magnetic coins of the same "grade comparison" are only stronger (in strength/range) if the inner core magnet is larger in diameter and thickness. Which means that the coin is bored out to a wider circumference and depth --- hense the higher price in labor and machining, plus cost of magnet. |

Larger diameters would naturally have larger area of attraction, but I believe that the strength of the magnet is directly proportional to its thickness as well as the Materials of Construction. Please correct me if wrong.
Thanks! Jim |

Yes Jim, that is basically what I meant when I stated:" ...only stronger (in strength/range) if the inner core magnet is larger in diameter and thickness."
Let's say that you have Magnet A (graded N42) and Magnet B (graded N52), and both magnets are the same width & height, then you would go for the highest grade (N52) for magnetic strength. Now, let say that you have two magnets of the same grade (N52), Magnet C is 1 inches in diameter (width & height) and magnet D is 2 inches (width & height). In this case, you would go for the larger magnet because it covers a larger surface area with the same magnetic rating. Both KREIS and JOHNSON PRODUCTS can state that their magnets are the highest rated (N52 material) but it comes down to who puts the largest magnet (width/thickness & height/circumference) with the highest rating into the inner core of the coin. The coin's diameter is set so it's a matter of who can "push the limits" with the best magnet technology and coin milling techniques. Thanks for the feedback. |

BanzaiMagic,
This post shouldn’t exclusively be about me but let me give you some of my background info: I have a long (21 years to date) and blessed upbringing in the world of magic. All that I know about magic comes directly or indirectly from “hanging out” with my Dad. My earliest and fondest memories consist of me and my Dad waiting for the UPS delivery truck almost every other Saturday for an order from Hank Lee’s Magic Shop --- it was like experiencing Christmas on a weekly basis for years on end. We would eagerly open the box and consume the contents. For the entire day, we would learn, creatively critique, routine and modify the contents --- because we were students of Magic, “partners in the art deception” and more importantly, a Daughter and Father building and maintaining a very special relationship. Magic was my Father’s vehicle to give me the gift and sense of wonderment about an otherwise mundane world. At the time, I had no clue to the extended education that I was being privilege to within the discipline of Magic and its numerous related fields of knowledge --- math, psychology, science, writing skills, project management and history, to name a few. Wow … it was never work, it was all play. Once again, I’ve been blessed. So yes, I do know a little about our shared art. I was probably the only teenage girl that was concerned about how to correctly do a DL or classic palm (still perfecting it) vs. dresses, lipstick and prom dates. And I do take pride in the fact that whenever my Dad did an ACAAN effect, he counted on me and only me to secretly do the Mnemonics. Because I’m interracial, no one ever detected that we were a daughter- father team --- hence, my user name: perceptions. Also, yes, the avatar picture is me. Introspectively, I post on this forum because I miss my Dad and I feel closer to him when I do... however “corny” that may be to some. Thanks for the feedback |
BanzaiMagic Inner circle 1339 Posts |
Not so corny.
I am doing the same thing with my 9 yr old grandson, and if he wants to, in a year or two with my 6 yr old grandson. The joy I am having in learning, performing and creating with my grandson is (second only to my wife) the greatest treasure in my life. Your post about your father has warmed my heart in a way that you could never have known. Thank you. Alan |

I totally agree!
Hope the child I'm having soon will have the desire to share this art like you did with your father. I read this thread to find info about magnetic coins, and here am I, smiling and deeply moved. Thank you for sharing your experience! |

Good story by perceptions...I enjoyed it. Thank you M'Lady.
I have found that most people that like magic don't care to learn it. They are happy with the amazement of it and that goes for your own kids too in most cases, who most times just want to know how it works. As wonderful as I think magic is, I can remember being about the only person that did magic on my block or in my neighborhood. I was the only one to take out the 1 magic book my school and neighborhood library had. I was the 1st, 2nd - 5th and 6th to 11th person to take out the book with no others listed in-between...I should've just kept it. The great secrets in Bobo's would've remained secrets forever in my old neighborhood. I would hope that my sons would've shared my love of the art but that didn't happen, as coin man, Tim Feher has also admitted regarding his own sons growing up now. He shows them magic all the time and at best they seem content to simply be his audience and nothing more. I can see how such shared love between someone and their kids would be special but it's also most likely quite unique in occurrence. I'm still hoping to leave what I know to some young apprentice but so far after all this time, I'm still the only magician on my block. And I have a library full of magic books and DVDs with not 1 person interested enough to check them out. Go figure.

I have one, but why not go with Johnson just as good, half the Price, no brainer.

I think the Kries super strong is the strongest in the market. You can do many things with it. Here is a routine using Kreis coins.

Here are some applications of the KREIS coins:
http://www.youtube.com/watch?v=gw_qU3COpns I haven't played around with the other magnet brands, but I can tell you that the Kreis coins are VERY strong. Had mine for three years and they haven't gotten any weaker. Available for $36 here: http://www.penguinmagic.com/p/S10203 |

I agree kreis's magnetic coins the super strong
are that indeed.I own them and use them a lot. There even dangerous if your not careful with them. Todd |

Kries Super Strong Magnetic Coins are by far the Best you can get for Special Effects.
No other coins on the Market Compare. I have sold them for many years. If you just want a standard magnetic coin,most all on the market will work. It depends what you are going to do with it. |
