What is another word for magnetic field?

What is another term for electric field?
A field of force surrounding a charged particle. Synonyms. field force field field of force electrostatic field.
How do you use magnetic field in a sentence?
Magnetic field sentence example
- What I have up there is just a power source and magnetic field .
- In the receiver there is a strong electromagnet, excited by a local current, which has in its circuit two annular air gaps, across which the magnetic field is practically uniform and constant.
How is a magnetic field created?
As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.
How do you find electric field?
In vector calculus notation, the electric field is given by the negative of the gradient of the electric potential, E = −grad V. This expression specifies how the electric field is calculated at a given point. Since the field is a vector, it has both a direction and magnitude.
How do you create a static electric field?
A static electric field (also referred to as electrostatic field) is created by charges that are fixed in space; A static magnetic field is created by a magnet or charges that move as a steady flow (as in appliances using direct current).
What is the electric field of a static charge?
Static electric fields are constant fields, which do not change in intensity or direction over time, in contrast to low and high frequency alternating fields. Hence, static electric fields have a frequency of 0 Hz. They exert a force on charges or charged particles.
How does static electricity push and pull things from a distance?
Static electricity can push or pull things without touching them. Static electricity is the buildup of the electrical charge in an object when it is rubbed against another object. Static electricity causes objects to stick together when they have opposite charges and repel when they have the same charge.
Does static electricity have a magnetic field?
Two types of forces may be distinguished: those arising from stationary electric charges, known as the electrostatic force, and those appearing only when charges are moving (as in an electric current in a conductor), known as the magnetic force….Static Electric and Magnetic Fields.

What is a constant electric field?
Firstly, the Electric field “E” is the slope of the potential, i.e., E=−dVdx. Therefore “constant electric field” means the potential is either increasing or decreasing at a constant rate (along the space).
Is force constant in a uniform electric field?
As field is uniform, force remains constant and acceleration remains constant.
