Every object or object on Earth is subject to a gravity force equal to P = m * g, where m is the mass of the object, g is the acceleration of gravity, g = 9.81 m / s2.
For a magnet to be able to lift an object, the electromagnetic force F of a given magnet must be no less than the force of gravity P acting on the body.
F ≥ P.
That is, with F = P, you can find the maximum body weight that can be lifted with a given magnet.
Let’s find the mass of such a body.
F = P = m * g.
Therefore, m = F / g = 200 / 9.81 ≈ 20 kg.
Answer: The magnet will lift 20 kg.
