Which is stronger, Gravitational or Magnetic forces?

Question

Which is stronger, Gravitational or Magnetic forces? A small magnet is able to lift a nail. Lifting is done against the gravitational force.

Answer 1

Gravitaty is by far the weakest of the forces.

In order from strongest to weakest they are:

Strong Nuclear force (Keeps the quarks in a proton, neutron, etc... together)
Weak Nuclear force (Keeps the atom together)
Electromagnetism
Gravity

Answer 2

Both magnetism and gravity can affect objects at a distance. Both get weaker as the objects get farther apart is different. This is why you feel the pull of gravity from the earth, but not from distance planets. It’s also why two magnets may move together if you set them near each other, but if you set them far apart nothing will happen. However, as two objects get far apart, the gravity between them goes down by a factor of four when you double the distance, but the magnetism goes down by (at least) a factor of eight. On the scale of the solar system, with planets far apart, gravity is much more important than magnetism.

When held a fraction of an inch (a few millimeters) away from the refrigerator, so that the magnet is not touching, the magnetic force on the magnet (from the refrigerator) is stronger than gravitational force (from the Earth).

Once you let the magnet go, it is still pulled onto the refrigerator's metal surface rather than falling to the ground. Magnetism is a strong force if the distance between objects is smaller than the distance between a magnet's two poles (North and South).

In a very specific, loval area, magnetism is the stronger force but over a large area (i.e. the universe) gravity is the stronger force.

Answer 3

magnetic forces are far stronger than gravitational.. in fact all forces in teh universe are about of equal strength, with the exception of gravity. The real question is why is gravity so much weaker than all over physical forces? Anyway, heres the proof...

A kitchen magnet can pick up a paperclip that the entire earth is attempting to hold down. Think about the scale difference between a kitchen magnet, and the entire earth. This gives you an idea of just how much stronger magnetic forces are than gravitational (by mass).

Answer 4

Magnetic

Answer 5

You can't really compare these 2 basic forces of nature. From your point of view, I'd say magnetic forces are easily visible and seem to have a stronger effect, but see it this way, magnetic forces affect only a few metals, but gravity affects EVERYTHING!

Answer 6

I'd say gravitational because even though a magnet can pull things together, gravity can pull magnets...magnets cannot pull gravity.

Answer 7

So, there is your answer. Magnetic forces are magnitudes greater than gravitational ones.

Answer 8

Magnetism. Some physicists believe that what we experience as gravity is just leakage from other dimensions.

Answer 9

1) Electric (electrostatic) 2) Strong nuclear force 3) Electric (electrostatic)

Answer 10

isn't it obvious that if a large magnet can pick up a car that it is stronger than gravity?
