There are many applications of permanent magnets.
Many children's toys have magnets to hold parts together, for example small trains.
There was a game called pick-up sticks done with magnets.
Apple Computer Co uses magnets to hold the power supply to laptops to help prevent damage when disconnecting the cord.
Hard drives have magnets as part of the movement mechanism.
Some of the more highly efficient motors and generators have permanent magnets. Also note that motors and generators can be made to be brushless to prevent the wear and maintenance on the brushes, often using permanent magnets. Windmill Generators.
Blackberry uses a magnet to sense when the cell phone is in the cradle and to shut off the screen of their cell phones.
Refrigerator Magnets.
Removable Signs & Labels.

Compasses.
Parts Retrievals.
Screwdrivers and tools that hold onto the screws.
Simple clasps on purses, cases, etc.
The uses of various types of magnets are almost endless.
What else can I help you with?
Where are permanent magnets located?
Permanent magnets can be found in various everyday items such as refrigerator magnets, electric motors, and speakers. They are also used in many industrial applications like generators and MRI machines.
How are temporary and permanent magnets alike?
Both temporary and permanent magnets generate a magnetic field, attracting objects made of magnetic materials. They both have a north and south pole and can be used in a variety of applications such as motors, generators, and sensors.
Are paperclips permanent magnets?
No, paperclips are not permanent magnets. They can temporarily exhibit magnetic properties when in the presence of a magnetic field, but they do not retain magnetism like permanent magnets do.
Are permanent magnets or electromagets used on doors?
Both permanent magnets and electromagnets can be used on doors. Permanent magnets are used in simple applications like cabinet doors, while electromagnets are commonly used in commercial settings for security doors or in access control systems. Electromagnets can be activated and deactivated as needed, providing greater control over door access.
What advantage do electromagnets have over other magnets?
Electromagnets can be turned on and off by controlling the flow of electricity, while permanent magnets have a fixed magnetic field. This makes electromagnets more versatile and suitable for a wider range of applications. Additionally, electromagnets can produce a stronger magnetic field than most permanent magnets.

How many types of magnets are there?
none
What type of magnets are the strongest?
Neodymium magnets are the strongest type of permanent magnets commercially available. They have high magnetic strength and are commonly used in applications requiring strong magnetic fields.
How are temporary and permanent magnets alike?
Both temporary and permanent magnets generate a magnetic field, attracting objects made of magnetic materials. They both have a north and south pole and can be used in a variety of applications such as motors, generators, and sensors.
What types of magnets are harder to magnetize but retain magnetism much longer?
permanent magnets
Are paperclips permanent magnets?
No, paperclips are not permanent magnets. They can temporarily exhibit magnetic properties when in the presence of a magnetic field, but they do not retain magnetism like permanent magnets do.

Are electromagnetic magnets permanent?
No, electromagnets are not permanent.
What are the differences between electromagnets and permanent magnets, and how do electromagnets differ from permanent magnets?
Electromagnets and permanent magnets differ in how they are created and their magnetic properties. Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets with a fixed magnetic field. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
What is the material used in permanent magnet?
The main material used in permanent magnets is neodymium, iron, and boron (NdFeB). These rare earth magnets are known for their strong magnetic properties and are widely used in various applications such as electric motors, generators, and hard disk drives.
What type of magnets are harder to magnets but retains magnetism much longer?
permanent magnets
