Use electro magnetic inside Which is self starter Out put can be used as electromagnetic is more effective Instant of wood use aluminium block and coil it with 370 turns Use 12 slot coil use make more effective than before
Thank you for your good comment Yes, it would be interesting to use electromagnetic, but here the purpose is to use a permanent magnet The use of aluminum causes reduced magnetic flux because: Aluminum cores have lower magnetic permeability compared to iron cores. This leads to a reduction in magnetic flux. Consequently, the efficiency of the generator decreases due to the reduced magnetic flux. Increased Ohmic Losses: Aluminum cores have higher electrical resistance than iron cores. This results in an increase in ohmic losses.
