but the current fall in
But my tests weren't so successful until now
to realize my semester project I need some help for the technical execution. I have the intention to regulate a magnetic field with a musical signal. The electromagnet (Intertec ITS-MS 5030) works with 12Vdc and 600mA. Voltage and current should be modulated by musical signals. The modulation of voltage and current should be executed by MAX/MSP and an Arduino board. But the maximum voltage of the Arduino board is 5V so I need to amplify the voltage.
The magnetic field decays exponentially I believe,
