Understanding Magnets

Magnets are materials that produce a magnetic field, attracting or repelling other magnetic materials. They are classified into two main categories: permanent magnets and temporary magnets. Permanent magnets retain their magnetism over time, while temporary magnets only exhibit magnetic properties when in the presence of a magnetic field.

Technical Features of Magnets

When evaluating magnets, several technical features are crucial. Below is a comparison table highlighting these features:

Feature	Description
Magnetic Strength	Measured in Gauss or Tesla, indicating the magnet’s ability to attract.
Material Composition	Common materials include Neodymium, Samarium Cobalt, Alnico, and Ferrite.
Temperature Resistance	The maximum temperature a magnet can withstand before losing magnetism.
Coating	Protects against corrosion; common coatings include Nickel, Zinc, and Epoxy.
Shape	Available in various shapes such as discs, blocks, rings, and custom designs.

Types of Magnets

Different types of magnets serve various applications across industries. The following table summarizes the main types of magnets and their characteristics:

Type	Description	Applications
Neodymium Magnets	The strongest permanent magnets available, made from an alloy of Neodymium, Iron, and Boron.	Used in motors, hard drives, and medical devices.
Samarium Cobalt	High-temperature magnets that resist demagnetization.	Ideal for aerospace and military applications.
Alnico Magnets	Made from aluminum, nickel, and cobalt, known for their temperature stability.	Commonly used in sensors and microphones.
Ferrite Magnets	Economical and widely used, made from iron oxide and strontium or barium.	Found in refrigerator magnets and loudspeakers.
Bonded Magnets	Made by combining magnetic powders with a polymer, allowing for complex shapes.	Used in automotive and electronic applications.
