Does The Size Of A Magnet Affect Its Strength
What Determines the Strength of a Magnet?
There are many different kinds of magnets. They come in different sizes, shapes, materials and strengths. They all generate a forcefulness called magnetism. This force is what allows them to attract or stick to certain metals. Yet some magnets tin't even concord a piece of paper to a fridge, while others can lift cars loftier upwardly into the air. And then, what is it that determines the strength of a magnet?
Blazon of Material
Every substance is made up of tiny units chosen atoms. Every atom has electrons. Electrons are constantly in motion. Their motility generates an electrical current, which causes each electron to act like a tiny little magnet. Most substances have an equal number of electrons spinning in opposite directions, which cancels out their magnetism. But some substances are strongly magnetic, which means virtually of their electrons spin in the same direction. These substances have high magnetic permeability and brand the strongest magnets. Fe, cobalt and nickel are among these substances. Neodymium fe boron (NdFeb) makes the most powerful magnets. Neodymium magnets are so powerful, in fact, that a NEO magnet weighing only a few grams can still attract up to ane,000 times its own weight.
External Magnetic Field
To plow a substance into a magnet, it must be exposed to the magnetic field of an existing magnet. The more powerful the external magnetic field applied, the stronger the resulting magnet will exist.
What about Size?
Does bigger mean stronger? When you magnetize a piece of iron, the n-seeking poles of the atoms align. The force generated by the aligned atoms creates a magnetic field. A larger piece of iron would have more atoms to align, potentially resulting in a stronger magnetic field than a smaller slice of the aforementioned material. However, in the case of an extremely long slice of iron, there is an increased risk that stray magnetic fields will misalign atoms and actually subtract the strength of the magnet's magnetic field.
Selecting the Correct Magnet
Although not a big factor in determining the strength of a magnet, size and shape tin matter just equally much depending on the awarding.
