Magnetic
When we talk about "magnetic", we are referring to the properties and behavior of magnets and magnetic fields. This includes the interactions between magnets, the creation of magnetic fields, and the effects of magnetic fields on charged particles and currents.
Key Concepts
- Magnetic Field: A region around a magnetic material or a moving electric charge within which the force of magnetism acts.
- Magnetic Force: The force exerted by a magnetic field on a moving charged particle.
- Magnetic Flux: The measure of the quantity of magnetism, taking into account the strength and the extent of a magnetic field.
- Magnetic Domains: Small regions within a magnetic material where the atomic magnets are aligned in a common direction.
- Electromagnetism: The interaction between electric currents or fields and magnetic fields.
