1. Given: A 25V DC linear motor operates in a steady state mode with a magnetic B-field of 0.8T, and a moveable “bar” with an effective length of 36 inches and a rail resistance of 0.025?. Find the back EMF (EIND) and the steady-state velocity of the bar for two conditions:

a. unloaded (frictionless)

Ufrictionless = __________ EIND_frictionless = __________

b. Loaded to 100 N

U100N LOAD =__________ EIND_LOADED = __________
