Assuming you had two cities, one of them an average real world City, and the other identical in every way, except that it's technology cannot advance beyond steam power (Cannot use combustion engines, guns, electricity, etc) And it has magic. These two different cities, both specialize in manufacturing and are trying to outpace each other. There are three main types of magic used by the Magic City:
Elemental Magic Allows the manipulation of elemental forces, the closest fictional comparison for overall power level I can give would be Avatar: The Last Airbender. training: it takes 1 year of study to be proficient in one element. It takes 4 years of study to be proficient in all four.
Body Magic(Necromancy) Allows people to summon the undead, and give them basic programming-like commands. They are minimally intelligent and non-sentient, but can be made to do repetitive tasks nearly indefinitely unless the body rots beyond usefulness or is damaged. These zombies are slightly weaker than an average human, but do not get exhausted. If the summoner of a zombie dies, their summoned zombies default to attacking the nearest living human. training: To summon one permanent zombie, it takes about two years of intense study of body magic. For every 2 years of additional study (equivalent difficulty to taking a college engineering class) you can summon an additional zombie.
Dimensional Magic People can create personal pocket dimensions for storing objects. These pocket dimensions have a maximum capacity in weight equal to a persons maximum lifting capacity. People can create portals from one place to another within line of sight, although this takes a lot of focus, and does not allow for any other tasks while holding a portal open. If a portal is closed on a non-living object, it will slice it through with a flawlessly smooth cut. Living objects are gently shoved outside before it closes. Portals can be enchanted on identically sized openings in such a way that the portals will be active perpetually, and can be moved, but will always be oriented in the same direction. Training: It takes 2 years of study to make dimensional portals of a consistent size and duration. It takes 8 years of study to be able to make permanent enchanted portals.
The Questions: Would these types of magic,while being restricted to steam power allow for the magic Powered City to outpace our Real World City in total manufacturing output?
What advantages and disadvantages would these types of magic provide?
