Think of the simple act of lifting a paper clip with a piece of magnet. The magnetic force of attraction is greater than the force of gravity in that case.

yes. Gravitational force is prominent only when extremely large masses are involved (Eg: Planets and stars). The magnetic field of a small bar magnet can overcome even the gravitational field of the Earth. In fact, Gravitational force is considered to be the weakest field force.

Electromagnetic forces are tremendrously stronger than gravitation forces!! Gravity is an extremely weak force!! A body dropped from a height does not penetrate the earth and reach the center ! The earth surface (elecro magnetic forces ) resists the gravitation forces ! It takes a earth size mass to create this gravity !!

Well yes, it usually is the case for magnets: their magnetic power is a lot greater than their gravitational field, and by several order of magnitude.
Now, if you meant can the earth's magnetic field become as great as its gravitational one, then the answer is no. Firstly, the earth's core is kept above the Curie point, which means the magnetic moment is not ferromagnetic, and thus a lot weaker than it could otherwise be. And secondly, earth's composition includes several elements that do not contribute to magnetism, but still add up to the gravitational one.

here is the experiment:
lay a steel nail on the floor,
(the entire earth is pulling down with gravitation)
place a small magnet above the nail and slowly lower it towards the nail until the nail leaps off the floor to stick to the magnet,
the magnet just overpowered the earth's gravity
(the key variable is how close the nail is to the magnet and how close it is to the earth's center)
magnetism is MUCH stronger than gravitation over short distances

BOTH THE GRAVITATIONAL AND MAGNETIC Forces depend upon the distance. thus the the strength of the magnetic force can be equal to or even greater than the gravitational force.
take example of large electro magnets lifting loads against gravity.

Magnetism is not a fundamental force. Instead, it occurs when you have a changing electric field (the electrical force is one of the fundamental forces).
Magnets can and frequently do overpower gravity on Earth. Consider several donut magnets strung vertically along a pencil. If you alternate the polarities of the magnets, they will support each other, overcoming gravity and spreading out along the pencil.

Magnetic force is muuuch stronger. However, gravitational forces act over longer distances than magnetic ones. Gravitational force varies by the inverse square of distance while magnetic varies by the inverse cube.

yes
consider a maglev train or a magnetic launcher (rail gun)
when an elevator is lifted by an electric motor, magnetic forces ar overcoming gravity

gravitational force is not that strong in the first place...so yeah
