Difference between static and magnetic attraction

In summary, static attraction is based on the type and quantity of charges, while magnetic attraction is dependent on the spin and alignment of particles. However, both are closely related and can be described using the electromagnetic tensor in quantum mechanics.

What is the physical difference between static and magnetic attraction?

Most simply the forces are described by the charges and domains respectively. Static attraction (re: Coulumb's law) depends on the type of charges (being opposite or similar) and the quantity of charge. Magnetic attraction, however, depends on the "spin" of the particles and the quantity and how well aligned those "spins" are. Note the quotation marks as the particles are merely described as "spinning" but really exist in a quantum state that we label as a spin.

That being said, the two are very similar and fundamentally linked (re: Lorentz Force). In quantum mechanics, it often makes more sense to use the electromagnetic tensor, which combines the aspects of both electric and magnetic forces.
 

What is a static attraction?

A static attraction is a force that exists between two objects due to their opposite electrical charges. This force does not change over time and can cause objects to stick together or repel each other.

What is a magnetic attraction?

A magnetic attraction is a force that exists between two magnetic objects or between a magnetic object and a magnet. It is caused by the alignment of magnetic fields and can cause objects to attract or repel each other.

How are static and magnetic attractions different?

The main difference between static and magnetic attractions is the type of force that causes them. Static attractions are caused by electrical charges, while magnetic attractions are caused by magnetic fields. Additionally, static attractions do not change over time, while magnetic attractions can be affected by changes in the magnetic field.

What are some examples of static attraction?

Examples of static attraction include rubbing a balloon on your hair and then sticking it to a wall, or rubbing a glass rod with silk and then using it to pick up small pieces of paper. The electrical charges on the objects cause them to stick together.

What are some examples of magnetic attraction?

Examples of magnetic attraction include two magnets sticking together, a compass needle pointing towards the Earth's magnetic field, and metal objects being attracted to a magnet. These are all caused by the alignment of magnetic fields.
