Can electric field exist without electric potential?
(a) No, just because the electric field is zero at a particular point, it does not necessarily mean that the electric potential is zero at that point.
A good example is the case of two identical charges, separated by some distance..
How is a magnetic field similar to an electric field?
Similarities between magnetic fields and electric fields: … Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract. Electric field points in the direction of the force experienced by a positive charge …
Can a magnetic field produce electricity?
Magnetic fields can be used to make electricity The properties of magnets are used to make electricity. … Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current.
Can a magnet power a light bulb?
Unfortunately, however, the current created by moving a magnet over a single wire doesn’t provide enough energy quickly enough to actu- ally light the bulb. To light a bulb, or to power anything else, you need to find a way to generate more power, which is the amount of energy produced in a certain time.
How does electricity affect magnetism?
Basically, the flow of electricity through a wire creates magnetic fields, and certain types of magnetic fields (they have to change with time) cause the flow of electricity. … The incoming electricity provides the power and generates magnetic fields which convert the power into motion.
Can electricity exist without magnetism?
Electric fields can exist without a magnetic field – consider a stationary point charge. Magnetic fields cannot exist without any E field component because there are no magnetic monopoles. … A stationary electric charge creates an electric field. A changing electric field creates a magnetic field.
