Magnetism

Yes. When a material is magnetized the magnetic domains are aligned.

The term for the attraction or repulsion between the poles of magnets is called magnetic force. This force is a result of the magnetic field that surrounds magnets and interacts with other magnetic materials.

If you bring a magnet close to iron pieces, you will observe that the iron pieces will be pulled towards the magnet. This attraction occurs because iron is a ferromagnetic material, meaning it can be magnetized and is attracted to magnetic fields.

Fire is attracted to oxygen, fuel, and heat. It requires these three components to ignite and sustain a flame.

The magnetic field generated by the piece of metal interferes with the Earth's magnetic field, causing the compass needle to deviate from pointing north. This happens because the compass needle aligns itself with the combined magnetic field in its vicinity.

Some ways to prevent demagnetization of magnets include storing them away from high temperatures, strong magnetic fields, and mechanical shocks. Additionally, using protective coatings or housings can help to shield magnets from external factors that may lead to demagnetization. Magnetizing the magnets along their preferred direction can also help to enhance their resistance to demagnetization.

Non-magnetic materials are those that are not attracted to a magnet. Examples include wood, plastic, glass, rubber, and cotton.

In the absence of interference from other magnetic fields or currents, a compass needle will align itself with the Earth's magnetic field and point towards the magnetic North Pole. However, it may not always point directly northward due to local magnetic anomalies or declination.

(electronics) A switching device consisting of three metallic layers (a paramagnetic layer between two ferromagnetic layers), whose action is based on electron spin and is controlled by a small magnetic field. Also known as bipolar spin device; bipolar spin switch; magnetic spin transistor; spin transistor; spin valve.

Sure. Like aluminum? Most commercially available aluminum contains some other materials, but only accidental traces of iron, if any. Copper, silver, and gold, same story.

You mean 'alloys' not metals - no pure metal contains iron aside from iron itself as they are just elements as opposed to compounds.

Iron-rich rocks can exhibit both normal and reversed magnetic polarity. When these rocks cool and solidify, the minerals containing iron align with the Earth's magnetic field. Over time, the Earth's magnetic field can reverse, causing the mineral alignment to also reverse, resulting in rocks with reversed polarity.

Magnetic domains are microscopic areas of a solid where the atoms all have their magnetic moments aligned. If these domains are randomly aligned then a ferromagnetic material like iron or nickel will not have any permanent magnetism. If these domains start to align with each other the bulk material will show permanent magnetism.

The area around a magnet where the force acts is the magnetic field.

Silver is a not magnetic metal - the most highly magnetic metal is iron - so no unless the cores of the coins are iron

Stroke a magnet down the length of the pin repeatedly. The proximity and movement of the magnet along the pin cause some of the iron molecules to become aligned like those in the magnet. The more strokes, the stronger the magnetic field in the pin will become, up to a certain threshold (the number of iron molecules available and able to align in the pin is limited).

Magnets and magnetic fields occur naturally in nature. However, i am unsure as to who first created the first commercial magnet.

When an electric current flows through a solenoid made of iron, the moving charges create a magnetic field. The iron core helps to concentrate and enhance this magnetic field, causing the solenoid to become magnetized. The alignment of the iron atoms in the core with the magnetic field results in a stronger overall magnetic effect.

No, fluorite is not magnetic. It is a non-magnetic mineral composed of calcium and fluorine.

No, Singapore coins are made of non-magnetic metals such as cupronickel or copper-clad steel, so they are not attracted to a magnet.

a magnet will pick up another magnet. magnet will stick to iron.

Fun Activity: if you have more than one magnet you can play a trick to your friends. you just need one magnet under a iron desk and put another magnet over on top of the desk. once you did that make sure that your friends doesnt see your hand under the desk and touching the magnet. slowly move the magnet under the desk so that it doesnt make lots of noise. then once you move the magnet under the desk the other magnet that is on top of it on the desk will move.

Yes, magnets can attract iron pills because iron is a magnetic material. The magnetic force of the magnet will cause the iron pills to be pulled towards it.

Yes, iron is a ferromagnetic material, meaning it can be magnetized and exhibit magnetic properties. When iron is brought into contact with a magnetic field, its atoms align to create a magnetic field, allowing it to be attracted to magnets and exhibit magnetic behavior.

There is some navigation accomplished by organisms that base their ability to do this kind of navigation on a small "compass" of iron oxide. It is this that permits them to sense magnetic fields. But most of animal navigation like this is accomplished by specialized biochemical structures that carry out ion transfers whose outcomes are influenced by magnetic fields. The study of the actual mechanism, the neurobiology, by which animals can sense changes in magnetic fields continues. And the biochemistry is complex. A link is provided to get you started on this topic. It takes a fair amount of chemistry and even more biochemistry to understand the actual mechanism themselves. And they're still not clearly understood. There's plenty of work to be done. A doctoral candidate who wishes to pursure the degree by working on animal navigation and magnetic sensing has some options open to him.

A technician should avoid using magnetized tools because they can interfere with electronic components and magnetic storage devices such as hard drives. This interference can lead to data loss or damage to sensitive equipment. It is better to use non-magnetic tools to prevent these issues.
