. Understand where you and others coming from. Its overwhelming, for someone who has hardly a clue on electronics, guess i came on here hoping for a miracle. As with the coul made, i coul;dnt understand all these laws and such, just trial and error on windings. In middle of making a prop, board 304 x 228 x 25mm, part routed out leaving 1mm below surface for electromagnet and the electronics, incorpotates, batteries, 1ch 433mhz receiver, capacitors, mosfets, other components ? an item (10-25grams) can be placed on the board (above the EM) Press of the transmitter, will repell the item as though some mystical force has thrown it, so a split second impulse of current. Possible recharge to repeat a senond or so after? It is much appreciated for those taking time out..

 

A "curved-arrow" may be enough information for some projects, but not for this one.

An Angle of Trajectory must be specified, such as,
horizontal, along the surface of the Table-Top,
or vertical, straight-up, perpendicular to the Table-Top,
or some general desired angle between the two planes.

How have You arrived at the approximate weight of the Object ?,
an appropriate Neodymium-Magnet will have to be procured and then weighed with the Container.

Also, the orientation of the Magnetic-Field of the Magnet must be specified before selection and purchase.
This can only be done after the desired Angle of Trajectory is specified.

Thank you for the time to reply. The angle not really taken in account, as just an effect of been thrown/tossed or flicked (suprize factor). 2 weights, one10gram other 35gram. Thanks

Hmmm Guess no further help please :-(

 

You Must be specific in describing/specifying/drawing exactly what You want.

Do You have a Video You could Link to ?

This is one of those things that might require a substantial amount of experimentation to satisfy your needs.

"" 2 weights, one 10gram the other 35gram. ""
What is this describing ?, we can't read your mind.

One Video is worth ~10,000 words.

A phot of the workings, which is what strugling with. Being use a 4 ch receiver, which i would replace with 1 ch QIACHIP Universal Wireless 433 Mhz DC 3.6V-24V Remote Control Switch 433Mhz. A photo of the workings, which is what strugling with. Just for own self satisfaction love to build... Appreciated

 

Ahh well was worth a shot :-(

 

There was an article in Popular Electronics about a mains powered high powered electromagnet system that used a resonant circuit to produce a very strong magnetic field that would work as a transformer with a separate copper disk, in which the induced AC magnetic field induced a current that created a second magnetic field that repelled the driving field, which would launch the isolated copper disk into the air a few feet. Of course the induced current was several amps, as was the driving loop current. So the theory is solid but the magnitudes of the power are much greater. With just a few amps you could launch a copper penny. BUT that amount of power is considerable.

AND a larger example would be the magnetic launcher on an aircraft carrier. The one prototype could throw a car a thousand yards. But that version used too much power, so the present linear motor versions are scaled way back.
