Electromagnetic Levitation System

Please visit http://zeltom.com/emls.aspx for more information. The electromagnetic levitation system is available as a kit or fully assembled unit.

This system uses an electromagnet to levitate a small magnet in midair. The small magnet levitates in the air indefinitely without any disturbance. The air gap is about 2 cm (3/4"). The supply voltage is 5 V and the supply current is about 0.3 A.

The vertical position of the levitating magnet is measured using a linear Hall effect sensor and the current in the electromagnet is actively controlled using a dsPIC30F3012 digital signal processor.

Three push buttons are included to adjust the vertical position of the levitating magnet and to apply a sinusoidal, square or sawtooth reference signal. Both the amplitude and frequency of the reference signal can be adjusted using the push buttons.

this is beautiful!! i was doing a project on levitating a steel ball electromagnetically trying to use this similar structure. how can I levitate a steel ball, instead of a magnet....and what type of sensor is suitable for that ? thanks al ot !!

@Bilal603

Thank you. I think the best way is to use an optical sensor to measure the position of the steel ball. You can also use a Hall effect sensor for this purpose but the signal to noise ratio will be very small.

@johnnytheprick but was the same mechanism used for his trick? I have a nice idea on how to use this.

@keoism

its already been done, youtube "chris angel levitation"

[rodstartube]

i tried levitating a stone. my project was a defecation

[keoism]

would it be possible to make it a big-scale and make people actually levitate?

[Bilal603]

@skydiverangel Thanks! that was helpful !! I will go for other than Hall Effect than...

It is possible to make the levitating object spin by a suitable excitation. The cost of the magnetic levitation system is $55 for the assembled unit and $43 for the basic kit. Please visit our website in the description for more information.

We also have another magnetic levitation system that can levitate up to 100 g. We can also customize the system according to your specifications and make a repulsive version of the system that allows levitation from a base. The magnetic levitation system in kit form requires basic soldering, electrical and mechanical assembly skills.

This magnetic levitation system is specifically optimized to work with the disc and sphere magnets (approximately 3 g and 8 g, respectively) listed on our website. The system intentionally limits the current through the electromagnet to reduce its power consumption and this imposes a limitation on the maximum weight of the levitating magnet. It can, however, levitate approximately 0-10 g additional weight and the shape of the levitating object can be arbitrary.
