#### Magnetism: quantities, units and relationships

The analogy with electric field strength is mathematical and not physical. An electric field has a clearly defined physical meaning: simply the force exerted on a 'test charge' divided by the amount of charge. Magnetic field strength cannot be measured in the same way because there is no 'magnetic monopole' equivalent to a test charge.

The SI unit for electric field strength is volt per meter (V/m). Newtons per coulomb (N/C) is also used as a unit of electric field strength. Electric fields are created by electric charges, or by time-varying magnetic fields. Electric fields are important in many areas of physics, and are exploited practically in electrical technology.

#### Magnetic field - Wikipedia

A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials. The effects of magnetic fields are commonly seen in permanent magnets, which pull on magnetic materials (such as iron) and attract or repel other magnets.Magnetic fields surround and are created by magnetized material and by moving electric charges (electric ...

Oct 06, 2013· When there is a large magnetic field, the Hall voltage will also be large as well. Similarly, when the magnetic field is small, the Hall voltage will decrease. Which, based on my results, will signify that there will be a direct relationship between the distance and the magnetic field strength. As one decreases, the other will decrease as well.

#### Notes on Electric Field Intensity and Electric Flux ...

Electric Field Intensity. The electric field intensity of a point inside the electric field of a charge is the force experienced by a unit positive charge (+1 coulomb) placed at that point. It is a vector quantity having unit N/C. Fig: Electric field intensity due to a point charge.

#### Exact relationship between electric field and intensity ...

To answer the question why are the constants so often omitted, I would like to supplement QtizedQ's point (that the constants are of less interest because often relative intensity ratios are used).Focusing on proportionality rather than a strict equation with constants also leaves "amplitude" ambiguous, where it could refer to either the electric field or the magnetic field.

#### How does voltage affect a magnetic field? | Socratic

Jul 02, 2014· A magnetic field is a phenomenon that can occur in one of two ways: it is induced by a current carrying wire, or it is generated naturally by the charge arrangement in a ferrous material. That said, voltage is not exactly directly related to a magnetic field. However, because current is a result of a voltage in a circuit, fluctuations in applied voltages could potentially cause simultaneous ...

#### Magnetic field, field strength, and flux density

Sometimes, people will be very precise and talk about either the magnetic flux density or the magnetic field strength.
