because they either attract or repel from each other depending on what side is against one side. You can do a lot with magnets for example stick things to the fridge or pick up loose pieces of metal or even shrapnel or broken medal that fell on the floor that you don't want someone to stand on.
They are essential for generating electricity.
Yes, magnets are useful for many applications including holding objects together, generating electricity, and even medical imaging.
Cupboards with magnets help to keep the doors closed securely and prevent them from swinging open. This can be especially useful in areas where there may be vibration or movement that could cause the doors to open on their own.
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.
which is the cheapest magnets
Not all magnets are made of metal. There are various types of magnets, including ceramic magnets (made of ferrite), neodymium magnets (made of neodymium, iron, and boron), and even electromagnetic magnets that are not made of metal.
because fridges are magnetic and for decoration
Electromagnets are useful because some machines need magnets that can stop being magnetic. In junkyards, some machines need to pick up metallic objects, so they need magnets that can turn on and off, which is where a electromagnet becomes useful.
No.If you break the magnet, it is still a useful magnet.
Electro magnets can be very useful to carry heavy loads of iron and metal from one side of a factory to another. Electro-magnets are formed by shooting electricity through a coil of copper.
Yes, magnets are useful for many applications including holding objects together, generating electricity, and even medical imaging.
A magnet can sort the ferrousmetalse.g., iron and steel, from the feed stream.
They pick up only certain materials and can be used to separate them.
The answer depends on what data of magnets! Their mass? strength of field? colour? metallic content? You do need to spend a tiny bit of time thinking about your question if you want a useful answer.
Electromagnets are more useful than permanent magnets because their magnetic field strength can be easily controlled by adjusting the amount of electric current flowing through them. This allows for greater flexibility in various applications, such as in electric motors, speakers, and magnetic levitation systems. Additionally, electromagnets can be turned on and off as needed, while permanent magnets have a fixed magnetic field.
Magnets are useful because they create a magnetic field that can attract or repel other magnets or magnetic materials. They are commonly used in various applications such as electronic devices, motors, generators, and medical equipment. Magnets also play a role in everyday items like refrigerator magnets and magnetic clasps.
Temporary magnets are useful because they can be easily magnetized and demagnetized. They can be turned on and off as needed, making them versatile for various applications such as in electromagnets, magnetic clasps, and magnetic sensors. Additionally, their magnetism can be controlled by adjusting parameters like current or temperature.
