A magnetizing force of 8000A/m is applied to a circular magnetic circuit of mean diameter 30cm by passing a current by a coil wound on the circuit.
If the coil is uniformly wound around the circuit and has 750 turns.
Find the current in the coil.
Le Chatelier's principle (H. Le Chatelier; 1888) If a system is in equilibrium, then any change imposed onto the system tends to shift the equilibrium to decrease the effect of
