Показать описание
Q.
Two similar coils of radius R are lying concentrically with their planes at right angles to each other. The currents flowing in them are I and 2I, respectively. The resultant magnetic field induction at the centre will be
a. (μ_0 I)/2R b. (μ_0 I)/R c. (√5 μ_0 I)/2R d. (3μ_0 I)/2R
