What is magnetic force of attraction?
Magnetism causes the forces of attraction or repulsion between magnets. It causes like poles to repel each other and opposite poles to attract.
Gravity ... attraction between any two masses -- Magnetic force ... attraction or repulsion between a magnet and magnetic materials, or between conductors carrying electric current -- Electrostatic force ... attraction or repulsion between electric charges, like the balloon and the wall, the comb and the bits of tissue, the socks and the shirts in the dryer, etc. -- Strong nuclear force ... attraction between particles in the nucleus of the atom; only works…
Iron is attracted by a magnetic force. Rust, a combination of iron and oxygen, is not attracted by a magnetic force. The iron in your body is essentially rust . . . that's why blood is red in color. Since the iron in your blood is not even partly pure iron, there is no magnetic attraction to it by any magnet.
A magnet and a metal paper clip have the strongest magnetic attraction when the distance between them is?
No. Think of the magnetic poles as merely gigantic magnets that produce strong magnetic force fields. Ordinary magnets are small duplications with tiny force fields of attraction. Also, remember that you can turn a magnet such that it repulses another, by reversing the direction of the force field within.
The attraction is called "nuclear force". Its details are still unclear, but one of its most important characteristics is that it is effective only over very short distances. In fact the attractive strong force is electrostatic and the repulsion is magnetic. The electromagnetic interaction is not so feeble as it is usually assumed.
Some forces do not involve physical contact between the bodies on which they act. They act through the space between them. Such forces are called Non-Contact Forces or Action-at-a Distance Force. They are of three types, namely, magnetic force, electrostatic force and gravhtational force. Magnetic Force -- The forces which a magnet exerts on iron objects is called magnetic forces. Electrostatic Force -- The force which result due to the repulsion of similar charges or…
