GATE 2024 Electromagnetic Fields Foundation Quiz 65

In the plane z = 5m a thin ring of radius, a = 3m is placed such that x-axis passes through it’s center. If the ring carries a current of 50 mA in 4 direction then the magnetic field intensity at point (0, 0, 1) will be ________ mA/m in a_z direction

For the current and closed path of figure given below, the value of is?

Planes z = 0 & z = 4 carry current k = –10a_x A/m & k = 10a_x A/m respectively. Determine H at (1, 1, 1)?

In the free space, magnetic field intensity at any point (ρ, ϕ, z) is given by H = 2 ρ² a_ϕ A/m. The current density at ρ = 2 m will be ………….. A/m² in a_z direction.
