jlo4 said:So I am somewhat confused on magnetic fields. Do they have a charge? Because I have come across many problems that involve either protons or electrons and whether or not they are deflected by the field. My question is if the fields do have a positive or negative charge, how are you suppossed to know what the charge is? Do you use the right hand rule for this or what? Any help to clear my understanding would be greatly appreciated!
A magnetic field is a physical phenomenon that is created by moving electric charges. It is a force field that surrounds a magnet or a current-carrying wire and exerts a force on other magnets or moving electric charges.
A magnetic field is created by moving electric charges. This can occur naturally in magnets, which have a north and south pole, or it can be created artificially by passing an electric current through a wire.
A magnetic field is created by moving electric charges, while an electric field is created by stationary electric charges. Additionally, magnetic fields can only exert a force on other magnets or moving electric charges, while electric fields can exert a force on any charged object.
The strength of a magnetic field is measured in units called teslas (T) or gauss (G). These units represent the amount of force exerted on a unit of charge in a given area. The stronger the magnetic field, the more force it will exert.
Magnetic fields have many practical applications, including in electric motors, generators, MRI machines, and compasses. They are also used in magnetic levitation technology, where magnets are used to lift and move objects without making physical contact.
