First some background. Magnetic fields were first defined in such a way that iron filings will point in the direction of (what became defined as) the field. The reason why filings point in the direction of the field is a little round about, but luckily the physics turned out pretty clean...
A magnet produces a vector field, the magnetic field, at all points in the space around it. It can be defined by measuring the force the field exerts on a moving charged particle, such as an electron. The force (F) is equal to the charge (q) times the speed of the particle times ...
What is magnetic field intensity in physics? What is an induced magnetic field? What is the simplest quantum field theory? What is superstring theory? What is the string field theory? What is electromagnetic energy? What is a non-uniform magnetic field?
What is magnetic field intensity in physics? What affects the strength of a magnetic field? What is the Earth's magnetic field? What does Earth's magnetic field do? What is a static magnetic field? What is the magnetic field formula?
2. Why is Earth surrounded by a magnetic field? There are magnetic materials found in Earth's crust. There are magnetic materials found in Earth's atmosphere. There are magnetic materials found in Earth's oceans. There are magnetic materials found in Earth's core. ...
Magnet is defined as a material that can produce its own magnetic field. There are three types of magnet: permanent magnet, temporary magnet, and electromagnet. Magnets are used in electric bells and generators.
Diamagnetism is caused by the orbital motion of electrons within atoms creating tiny current loops, which produce weak magnetic fields, according to HyperPhysics. When an external magnetic field is applied to a material, these current loops tend to align in such a way as to oppose the applied ...
A bar magnet is a rectangular piece of an object that shows permanent magnetic properties and are made from the ferromagnetic substance. Cylindrical and rectangular bar magnets are the types of bar magnet. They are used in educational institutes.
The strength of a dipole is measured as the magnetic. The moment is a vector, meaning it has a magnitude, or size, as well as a direction. When considering magnetic poles, such as those in a bar magnet, the magnetic moment (m) is defined as the strength of the poles (p) multiplied...
Magnetic Flux: In physics, magnetic flux is an important component of electromagnetic energy. A fluxmeter measures a unit called the weber (Wb). The flux can flow through a magnetic circuit. Answer and Explanation: Magnetic flux is the overall magnetic field of an object. If you look at the...
