Magnetic field due to currentHard
Question
A large plate with uniform surface charge density σ is moving with constant speed v as shown in the figure. The magnetic field at a small distance from plate is :
Options
A.μ0 σ v in magnitude
B.
in magnitude
in magnitudeC.Perpendicular to plate
D.Parallel to plate
Solution
Current flowing per unit length = σ
= σvBy Ampere′s law
Bl + Bl = μ0σv1 ⇒ B =
