Electromagnets are generally weaker than permanent magnets?
Depends on the size. One good example of a powerful electromagnet is the one used to lift cars at junk yards. Permanent magnets are not used for that due to the sheer power needed to lift cars. Also, electromagnets can be turned ON and OFF making them useful in picking up and then dropping the junk cars as needed. Another big example of electromagnets are the ones used on power generators to generate electric power.
