Hello,(adsbygoogle = window.adsbygoogle || []).push({});

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.
