A way to imitate gravity in space

I have an idea for a light weight, super flexible magnetic suit that molds to your body, and is magnetically attracted to the floor of the spaceship.

Is it possible to strengthen this magnetic attraction and allow the an astronaut wearing the suit to experience equal gravity to that on Earth, or greater, yet allow them to be as agile as if the weren't wearing it at all?

Why would the suit need to mold to your body if its sole purpose is to be attracted to the floor. Why not magnetic boots?

You could, in theory, use an electro-magnet placed in a boot that has some type of automatic variable resistance to allow for different strengths. If it is too strong, you can't move. If it is too weak, you float away.

How do you envision this working exactly?

I don't want boots because I want the gravity (Force) to be felt all over the body, so that everything we do takes effort. Training in this suit could allow us to easily navigate planets with higher gravity than ours, right?

The suit won't stop you from eating because you can take it off. Your can breathe through a hole in front of your mouth and nostrils.

This would require an advanced fabric, thats like a flexible magnetic plate, that can bend and curve like cloth.

Ok, I had assumed that you meant to use the suit in low/zero gravity environments. In tis case, why not just use weighted suits for training?

Though a suit could be made of flexible magnetic sheets, it would be very weak, magnetically speaking. For instance, consider the difference in attraction between a person's head and feet while standing.

I do mean in space.

With enough energy you can do anything.

Won't work. There is no way to work it so that you would have equal attraction to the floor for all parts of the suit.

Re: A way to imitate gravity in space

Like Freeztar pointed out there would be trouble trying to make to field constant over your whole body.

The best way to imitate gravity is to incorperate a spinning cylinder into your ships design. To imitate higher gravity you can either have the room taper at one end, decreasing to radius of the cylinder. This would make you rotate faster and hence 'feel' more gravity.

Re: A way to imitate gravity in space

Won't work. Even if you could get the magnetic attraction even for the entire suit, it won't "feel" like gravity.

Imagine, your entire body would be pulled down to the floor at what would feel like 1g to your skin, being the only part of your body physically connected to the suit. But your intestines would still be weightless. Your stomach and its contents would be in free fall, but your body would be at 1g. Also, your skeleton won't really experience it, so it won't do anything for bone density loss. I think this particular setup will make me extremely nauseous. I will paint the spacecraft with my stomach lining in no time flat.

I think normal weightlessness experienced by astronauts would be more comfortable, or simply rotate the entire space vehicle so that centrifugal forces would simulate 1g.

I see.

I already knew about the rotating centrifuge, it seems a little expensive though. I know about more expensive ways to imitate gravity, but none that are less expensive.
