The direction of the magnetic field is +z direction.
The magnitude of the magnetic field is 100πM/3Q units.
The direction of the magnetic field is -z direction.
The magnitude of the magnetic field is 50πM/3Q units.
The correct options are
A. The direction of the magnetic field is -z direction.
C. The magnitude of the magnetic field is 50πM/3Q units.
Sol. (A, C)
So magnetic field is along -ve, z-direction.
Time taken in the magnetic field = 10 × 10⁻³ = 10⁻² s
B = πM/6Q
B = πM/(60 × 10⁻³Q) = 1000πM/60Q = 50πM/3Q
