Magnetic force is the attractive or repulsive force exerted between magnets or magnetic materials. For example, when a magnet is brought close to a collection of iron balls, the magnetic force causes the balls to be attracted towards the magnet. This phenomenon illustrates the ability of magnetic forces to influence and manipulate magnetic materials, showcasing magnetism in action.
The attraction of two magnets is a result of magnetic force pulling them towards each other. Magnets have two poles, a north pole and a south pole. Unlike poles attract, so when the north pole of one magnet faces the south pole of another, the magnetic force causes them to be drawn together.
The repulsion of two magnets occurs when like poles (two north poles or two south poles) face each other. According to the principles of magnetism, like poles repel each other. The magnetic force generated between the similar poles pushes them away from each other.
When nut bolts, made of ferromagnetic material, come into the vicinity of a magnet, they are attracted to it due to magnetic force. The magnet induces a magnetic field in the metal, causing the nut bolts to be drawn towards the magnet.
When a paper clip, typically made of steel, is brought near a magnet, it becomes attracted to the magnet. The magnetic force affects the magnetic domains in the steel, aligning them in a way that causes the paper clip to stick to the magnet.
When coins, typically made of non-magnetic materials like copper or aluminum, appear attracted to a magnet, it may be due to an electromagnetic effect. Some coins may contain small amounts of magnetic material or become temporarily magnetized in the presence of a strong magnetic field, causing them to be attracted.
If a wrench, made of ferromagnetic material (such as steel), sticks to a magnet, it’s because the magnetic force is acting on the metal. The magnetic field induces magnetism in the steel, causing the wrench to be attracted to the magnet.
Similar to the wrench, if iron keys stick to a magnet, it indicates the presence of ferromagnetic material in the keys. The magnetic force induces magnetism in the iron, causing the keys to be attracted and stick to the magnet.
When iron powder is brought near a magnet, it is attracted due to the magnetic force acting on the individual iron particles. The magnetic field aligns the iron particles, causing them to be drawn toward the magnet. This phenomenon demonstrates the ability of magnets to attract and manipulate small magnetic particles.
