There is a electron in empty space,and two person,person-1 and person-2.person-1 is at rest with respect to electron and person-2 is at motion with respect to electron(with uniform velocity).will the person-2 experience any magnetic field?then what about person-1?i have studied that moving charge will produce magnetic field.then w.r.t person-2 the charge is moving.then it must produce magnetic field.if it produce magnetic field will the person-1 can experience it? If person-2 begins an accelerated motion w.r.t electron will the electron produce any electro-magnetic wave?if it produce any electro-magnetic wave will the person-1 can detect it?

please clear the doubt.

TopNewestfor the first case ---( person2 moving with v velocity) with respect to that frame of reference , yes there will be magnetic field , but person1 s frame will have electrostatic field only ... incase of accelarating motion also electromagnetic field is there in the 2nd person's reference frame ..

that means a charge only produce eletric field.the other two are caused by change in eletric field.

STATIONARY charge produces electrostatic field only while moving charge can produce both electric and magnetic field .. what matters is the reference frame

"the other two are caused by change in electric field" i wonder if biot savart law can be derived from electric gauss law and ampere maxwell law...

Google "Lorentz Transformations of Electromagnetic Fields". Person 1 and Person 2 will measure the electromagnetic field differently.

i will try to help, sist magnetic field is cause by moving electron not the person, and electricity field is cause by rest electron. so, cause the electron at rest with respect to person 2, person 2 won't experience any magnetic field.it is reversed at person 1 condition if it's just the person who is moving respectively to electron, so we can assume that the electron is at rest, I wonder whose moves that we have to consider if the electron is accelerated, it will produce an energy that will emit such radiation that we known as Electro magnetic waves, if the electron is at rest, there is no electro magnetic waves indeed

you said that the electron will emit energy,in form of electro-magneticwaves.that waves must reach at both the persons.but the charge is not moving w.r.t person-1.
