The flux density at a point in space is given by B = 4xa_x + 2kya_y +8a_z Wb/m². The value of constant k must be equal to

Two magnetically uncoupled inductive coils have Q factors q₁ and q₂ at the chosen operating frequency. Their respective resistances are R₁ and R₂. When connected in series, their effective Q factor at the same operating frequency is

A steady current l is flowing in the – x direction through each of two infinitely long wires at as shown in the figure. The permeability of the medium is μ₀. The -field at (0, L, 0) is

Consider a one-turn rectangular loop of wire placed in a uniform magnetic field as shown in the figure. The plane of the loop is perpendicular to the field lines. The resistance of the loop is 0.4Ω, and its inductance is negligible. The magnetic flux density (in Tesla) is a function of time and is given by B(t) = 0.25 sin ωt, where ω= 2π × 50 radian/second. The power absorbed (in watt) by the loop from the magnetic field is ______.
