* Strength and Control: Electromagnets can be very strong, capable of lifting the heavy weight of a car. Crucially, the magnetic field can be turned on and off at will. This allows for precise control – the car can be lifted, moved, and then released safely at the desired location. This is a much safer and more efficient method than using other means.
* Versatility: Unlike cranes with hooks which require precise placement, an electromagnet can attach to various parts of a car body (provided they are ferrous – made of iron or steel).
* Speed and Efficiency: The process of attaching and detaching is relatively quick, speeding up the overall process of moving and stacking cars.
* Reduced Risk of Damage: A properly designed electromagnet, when used correctly, is less likely to damage the car's body compared to other methods of lifting and moving which might scratch or dent the car.
In short, the combination of strength, controllability, and speed makes electromagnets the preferred method for handling large quantities of scrap metal cars in a junkyard.
