Question
The image below shows four hypothetical magnetic field configurations. How would you create field A? There may be more than one correct answer.
None of these A uniform electric field out of the screen, increasing in magnitude A uniform electric field out of the screen, decreasing in magnitude A uniform electric field into the screen, increasing in magnitude A uniform electric field into the screen, decreasing in magnitude A uniform magnetic field out of the screen, constant in time A uniform magnetic field into the screen, constant in time A stationary positive electric charge A stationary negative electric charge O)) {(O /M / A. H. C. D.Explanation / Answer
In this case, the uniform electric field out of the screen with increase in its magnitude as in the case of parallel plate capacitor. at the same time the magnetic field will radiate into the screen from flemin's left hand rule as in the case of solenoid.
The uniform electric field means that the charges are cancelled in the path i.e. there will be two positive charges that gets cancelled by two negative charges , it means the charges are either positive or negative charges. this can be determined by inverse square law .
As mentioned above the parallel plate capacitor offers a uniform electric field when it is in dielectric mediumpresent between the two plates.
The fleming's left hand rule gives the direction of magnetic field as in ths case. so, by this way we can create the electric field by using uniform electric field like that in the case of parallel plate capacitor.
inverse square law is giiven by:
F=K*q1*q2/r2
