Is it true or false that an electric charge creates a magnetic field?
Opposites attract, like charges repel each other.
When there is no current passing through a conductor you say magnetic field is zero but in a conductor charges are in motion then why is there no magnetic field?
When there is no current passing through a conductor, charges are stilll in motion, but they are disorganized and not flowing. The magnetic fields by all of those random movements cancel each other out. That is why there is no magnetic field in a conductor with no current, even though there is movement in the charges.
What is magnetism produced by?
Magnetism is produced by the alignment and movement of electric charges, specifically electrons, within a material. In some materials, such as iron, nickel, and cobalt, the alignment of these charges creates a net magnetic field that can attract or repel other magnetic materials.
Does earth's magnetic field only affect other planets?
No. Earth's magnetic field only affects earth, not other planets.
What do electric and magnetic fields contain and transport?
Electric and magnetic fields contain energy and information. They transport this energy and information through space. In the case of electric fields, they are generated by stationary electric charges and transport energy and information by interacting with other charges. Magnetic fields, on the other hand, are generated by moving charges or changing electric fields and also transport energy and information through their interactions with other magnetic fields or moving charges.

Does Magnetic forces act when electrons move?
Yes. To be more accurate, a magnetic field is caused whenever there are moving electrical charges. Even the magnetic field in a permanent magnet are caused by more electrons moving around their atoms in one direction, than in the other.Yes.

What creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields. "A magnetic field can be created with moving charges, such as a current-carrying wire. A magnetic field can also be created by the spin magnetic dipole moment, and by the orbital magnetic dipole moment of an electron within an atom." A magnetic field can be produced by either a permanent magnet, or an electromagnet, the latter requiring suitable energization to function.
What electric charge crates a magnetic field?
Moving charges produce magnetic fields.Answer 2In other words, when the charge moves along a conductor it creates an electric current. The current induces a magnetic field around the conductor.
What surrounds electric charges and exerts force on other charges?
An electric field surrounds the charge and exerts force on other charges.
Why do magnets work?
Magnetic attraction occurs due to the effect of magnetic fields on electrical currents. An electric current would be the flow of electric charge (positive or negative depending on the amount of electrons present). A magnetic field is produced by moving electrical charges to effect other charges (basically).
How are magnetic poles and electric charges similar?
Main similarity: Like charges repel each other, different charges attract each other.Main difference: Magnetic "charges" can't be separated. At least, so far it has not been achieved.
What is similar between force fields and magnetism?
Force field refers to the lines of force one object exerts on another object or a collection of other objects. Note that force fields does not exist in reality, but are really a construct that allows scientists to visualize the effects of objects on other objects; in other words, it makes the math easy. Examples of force fields: Newtonian gravitational field, global Gravitational field, A conservative Electric field, A static Magnetic field. A magnetic field is a field that permeates space and which exerts a magnetic force on moving electric charges and magnetic dipoles.
How does changing current affect the magnetic force on a wire suspended in a magnetic field?
Current passing through a wire in a magnetic field creates its own magnetic force in some direction. If you increase the current, force will be increased. If the direction of current is changed, direction of force will also be reversed. Direction of current is found by applying right hand rule.
What is meant by electric and magnetic field?
A magnetic field is a area in which magnetic objects are pushed or pulled. It is caused by the alignment of parts of atoms.A field of force associated with changing electric fields , as when electric charges are in motion. Magnetic fields exert deflective forces on moving electric charges. Most magnets have magnetic fields as a result of the spinning motion of the electrons orbiting the atoms of which they are composed; electromagnets create such fields from electric current moving through coils. Large objects, such as the earth, other planets, and stars, also produce magnetic fields. See Note at magnetism.
