I am dealing with this problem that I am not completely sure about and any mistep would let to something ufixable so I am asking somebody better versed in these kind of things and I hope somebody would have the patience to answer my question in detail.
As the title suggest I need to drive an electromagnet using audio amplifier and I am trying not to destroy it.
The amplifier has Hammond Manufacturing 125DSE audio trasformator (http://www.digikey.com/product-detail/en/125DSE/125DSE-ND/454501) and has 4 / 8 / 16 ohm outputs. The speaker curently attached to it is 60W, 8ohm.
I would like to use this (http://www.ebay.com/itm/12V-DC-22-LB-10kg-Electric-Lifting-Magnet-Electromagnet-Solenoid-Lift-Holding-/360519627296?hash=item53f0a4f220) electromagnet with following specifications:
- Input Voltage: 12V DC
- Current: 0.42A
- Power Consumption: 5W
- Diameter: Approx. 30 mm
- Center Diameter: Approx. 12 mm
- Wire Length: Approx. 23 cm
I know that electromagnet on itself is behaving differently than electroagnet in speaker but Im not sure about anything else. Could you reccomend an electromagnet that would work and would not overheat after few hours?
Thank you very much in advance for any kind of answer.
(also sorry for my english, Im not a native speaker)
Thank you for the answers. For clarification:
The electro magnet I mentioned is just an example, the real question is, what magnet that would work would you recommend?
What I am trying to achieve is to control intesity of the electro magnet with input from sound (guitar, effects and so on). It does not have to be particulary strong but it would be better. I wont be lifting anything just controling the field.
