Lift a weight up with an EM switch

  1. Mar 13, 2017 #1

    My question is simple. Let's suppose you have an electromagnetic coil with a magnetic weight in the center of it. This coil is energized, and the weight is lifted up vertically.

    Now, my weight is 30 kgs. I want to lift it to a height of 1 meter. How do I calculate how much power is required to do this? How do I calculate it in terms of Watts?

    For the mods: This is not a homework question. I am trying to understand something.

    There is no easy relation for this, it depends on your coil, the weight, and the overall geometry.
