What are some techniques for reducing the size and weight of electromagnets without sacrificing performance?

The range of electromagnets and electromagnetic components is widely used for door system automation on all types of rail vehicles. This creates a magnetic field around the coiled wire, magnetizing the metal as if it were a permanent magnet. Electromagnets are useful because you can turn the ... ... used to turn a propeller-like piece called a turbine ... When the rotor turns, it causes the field poles (the electromagnets) to move past the conductors mounted ... The best safety tips for electromagnets' uses · 1.
