Magnetic force
Magnetic force demonstration

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.

Examples

Magnet

Magnetic force example - magnet (different poles)
Two magnets attract due to the magnetic force when their opposite poles face each other

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.

Magnetic force example - magnet (same poles)
Two magnets repel due to the magnetic force when their like poles face each other

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.

Nut

Magnetic force example - nut
Nut bolts are attracted to a magnet due to the magnetic force acting on the ferromagnetic material

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.

Paper clip

Magnetic force example - paper clip
A paper clip is attracted to a magnet when brought closer, responding to the magnetic force

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.

Coin

Magnetic force example - coin
Coins may be attracted to a magnet due to small amounts of magnetic material or temporary magnetization

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.

Wrench

Magnetic force example - wrench
A wrench sticks to a magnet as the magnetic force induces magnetism in the ferromagnetic material

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.

Key

Magnetic force example - key
Iron keys stick to a magnet due to the magnetic force acting on the ferromagnetic iron in the keys

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.

Iron powder

Magnetic force example - iron powder
Iron powder is attracted to a magnet, demonstrating the magnetic force’s ability to manipulate small magnetic particles

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.
