No. Magnetic force and gravitational force are completely different things,
and they don't interact. Nothing can resist, "defy", or shield against gravity.
magnet
Not a magnet, no. But it does attract the Earth and this is due to gravity.
Yes, gravity does have an effect on a magnet, but it is typically very small compared to other forces acting on the magnet, such as magnetic forces. Gravity affects the entire mass of the magnet, pulling it towards the Earth, but the magnet's magnetic properties are typically more noticeable in everyday interactions.
No, but certain properties of gravity can simulated, using a magnet.
The center of gravity of a magnet is typically in the middle of the magnet, where the mass is evenly distributed. For a coin, the center of gravity is near the geometrical center as long as the mass is evenly distributed.
The magnet is in the world because magnetism is one of the fundamental forces of the universe, along with gravity.
A man cannot resist the gravitational pull of Earth, as gravity is a fundamental force of nature. Gravity is what keeps us grounded to the Earth's surface and allows objects to maintain their position in space.
The force of attraction between the pin and the magnet is greater than the force of gravity acting on the pin. As a result, the pin moves upwards towards the magnet instead of being pulled downwards by gravity.
Gravity. A parachute uses the force pushing up on a large area of silk to resist the force of gravity, allowing for a controlled descent and landing.
They don't. They jump higher and further because they are stronger and better at doing so, not because they can resist gravity.
Concentric
No, gravity is not the opposite of inertia. Gravity is a force that pulls objects towards each other, while inertia is the tendency of an object to resist changes in its motion.
