Recall from EN1216 that for a long solenoid, the flux density is given by: HONI B l As we saw in the class (see section 4) a modified expression can also be derived that eliminates the need for the 'long' solenoid assumption: R α1 Р â B = HONI 2l (cosa₂-cosα1) 1 Compare the results obtained using equations (1) and (2) and state which solution you would expect to give the best approximation to the real coil behaviour.arrow_forwardI need immediate help with my SIMULINK model.
