Yes. Kinetic energy is a form of mechanical energy and friction will turn that kinetic energy into heat.
        
             
        
        
        
Answer:
The combined magnetic force of the magnetized wire coil and iron bar makes an electromagnet very strong. In fact, electromagnets are the strongest magnets made. An electromagnet is stronger if there are more turns in the coil of wire or there is more current flowing through it.
 
        
             
        
        
        
Objects that let in light and blurry images are translucent.
