I need to calculate the power needed to move a linear solenoid. I have a 12v linear solenoid. On the end of it is a small metal plate. 1/2" space, then a neodymium magnet in a fixed position. I want to actuate the solenoid away from the magnet. There is a 2.1lbs pull force between the plate and the magnet. I used a digital fishing scale, attached it to the rear of the solenoid, slowly pulled, and recorded the measurement when the magnetic force broke. What supply, or requirement for a supply, is need to actuate the solenoid? I can change solenoids also to meet the requirement for the supply. Please throw out some theories so I can test them. Thx.
