Research i can view on magnetism

In summary, magnetism is a physical phenomenon caused by the movement of electric charges within a material, resulting in objects being able to attract or repel each other based on their magnetic fields. It works through the alignment and movement of electrons within a material, creating a magnetic field that can be used in everyday applications such as electric motors, generators, and medical devices. There is a difference between permanent magnets, which have a consistent magnetic field, and electromagnets, which are created by passing an electric current through a wire. While everyday exposure to magnetic fields is generally not harmful to humans, long-term exposure to high levels may have potential health risks.

Anyone know of any good papers, research i can view on magnetism, also any equations for working out the force of one etc would be fantastic.

Sounds like you should start with some basics - any general physics book will do. Three that come to mind are Halliday & Resnick Physics, Feynman Lectures on Physics and Halliday & Resnick & Walker Fundamentals of Physics.

Any first-year physics book will have a section on magnetism.
 

FAQ: Research i can view on magnetism

What is magnetism?

Magnetism is a physical phenomenon in which objects can attract or repel each other based on their magnetic fields. It is caused by the movement of electric charges within the material.

How does magnetism work?

Magnetism is the result of the alignment and movement of electrons within a material. When the electrons move in the same direction, they create a magnetic field that can attract or repel other objects with magnetic properties.

What is the difference between a permanent magnet and an electromagnet?

A permanent magnet is a material that has a consistent magnetic field and retains its magnetism without an external source. An electromagnet, on the other hand, is created by passing an electric current through a coil of wire, which generates a magnetic field. The strength of an electromagnet can be adjusted by changing the amount of current flowing through the wire.

How is magnetism used in everyday life?

Magnetism is used in a wide range of everyday applications, such as in electric motors, generators, speakers, and compasses. It is also used in medical devices like MRI machines and in data storage technologies like hard drives.

Can magnetism be harmful to humans?

In most cases, the magnetic fields produced by everyday objects are not strong enough to cause harm to humans. However, exposure to strong magnetic fields, such as those found in MRI machines, can cause temporary side effects like dizziness or nausea. Long-term exposure to high levels of magnetic fields may also have potential health risks, but more research is needed to fully understand the effects.
