Question

An electron moves along vertical line and towards observer, the pattern of concentric circular field lines of
magnetic field which is produced due to its motion :-
(1) ACW, In horizontal plane
(2) ACW, In vertical plane
(3) CW, In horizontal plane
(4) CW, In vertical plane
Explain.​

Answer 1

Answer:

the pattern of concentric circular field lines of  magnetic field which is produced due to its motion ACW, In horizontal plane

Explanation:

As we know by Biot Savart law the magnetic field due to a moving charge is given by

$B = \frac{\mu_0qv sin\theta}{4\pi r^2}$

now the magnetic field lines in the concentric circle form is required

so we will have

$B = \frac{\mu_0 ev}{4\pi r^2}$

here we know that electron is moving towards the observer so the electric current will flow away from the observer

so here we will have

magnetic field in Anticlock wise direction in horizontal plane
