Magnetic 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.

The electromagnetic levitation system controls the magnetic field generated by an electromagnet to levitate a small magnet in midair. The small magnet levitates in the air indefinitely without any disturbance. The vertical position of the levitating magnet is measured using a linear Hall effect sensor and the current in the electromagnet is controlled using a digital signal controller. The system has three push buttons 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.

How much magnets did you use for this?

[skydiverangel]

@wusimon51

It uses a permanent magnet and an electromagnet.

[wusimon51]

Is it a power generator causing the attraction?( And batteries?)

[skydiverangel]

@wusimon51

The power supply is used to power the system. A standard 9 V battery can also be used for this purpose. The attractive force is generated by the electromagnet.

Awesome!

AWESOME - AMAZING!!!  awesmazing..

@win2rgirl

As far as I know, some stainless steels are magnetic and some are nonmagnetic. You can use any nonmagnetic material.

@skydiverangel so can i make the stand out of steal? or does it affect the project?

@TOMarshad

1. It draws approximately 120 mA with the disc magnet and 150 mA with the sphere magnet when the supply voltage is 7.5 V.

2. The voltage applied to the electromagnet is adjusted based on the measured position of the levitating magnet to achieve stable levitation.

3. Please visit the website provided in the video.

[TOMarshad]

have a lot of questions to ask...

1.How much power is required for 10 hrs of continuous levitation

2.Why doesn't the magnet fall down or move towards the side

3.can u provide a plain pcb diagram for this project plz...

Well done colleague ... engineering is a blessing....
