In electromagnetism, various quantities are measured using specific units, which can be classified into two main systems: the International System of Units (SI) and the centimeter-gram-second (CGS) system. Here's an overview of key quantities and their units in the SI system, commonly used in modern physics: 1. **Charge**: - **Unit**: Coulomb (C) - The basic unit of electric charge.
The unit of electrical inductance is the henry (symbol: H). One henry is defined as the amount of inductance in a circuit in which a change in current of one ampere per second induces an electromotive force of one volt. Mathematically, this can be expressed as: 1 H = 1 V·s/A Where: - V is volts, - s is seconds, - A is amperes.
The unit of magnetic flux is the weber (Wb) in the International System of Units (SI). One weber is defined as the amount of magnetic flux that, when linking a circuit of one turn, produces an electromotive force of one volt when the flux is reduced to zero at a uniform rate in one second.
The unit of magnetic flux density is the tesla (symbol: T). One tesla is defined as one weber per square meter (1 T = 1 Wb/m²). In the International System of Units (SI), the tesla is the standard unit used to measure the density of magnetic flux in a given area.
The unit of magnetic induction, also known as the magnetic flux density, is the tesla (symbol: T) in the International System of Units (SI). One tesla is defined as one weber per square meter (1 T = 1 Wb/m²). Another commonly used unit, especially in electromagnetic contexts, is the gauss (G), where 1 tesla is equal to 10,000 gauss (1 T = 10,000 G).
