Magnetic Field of a Toroid

Описание к видео Magnetic Field of a Toroid

A 2.90 mH toroidal solenoid has an average radius of 5.40 cm and a cross-sectional area of 2.20 cm^2.

a) How many coils does it have? In calculating the flux, assume that B is uniform across a cross section, neglect the variation of B with distance from the toroidal axis. Express your answer as a number of turns.

b) At what rate must the current through it change so that a potential difference of 2.60 V is developed across its ends? Express your answer in amperes per second.
