difference between electromagent and solenoid... or both are the same?
Answers
Answer:
An electromagnet is an electrically induced magnet. ... A solenoid is a cylindrical coil of wire acting as a magnet when carrying an electric current. A solenoid is the same as an electromagnet but without a core of material that can be magnetised i.e. iron (which is magnetically soft).
Solenoid is a metal bar coiled around with wire. On passing current, the solenoid induces magnetism. This magnetism's power can be adjusted by number of turns wire makes and the amount of current.
Whereas an electromagnet is simply a metal bar that induces magnetism when current flows through it.
So you can say both are same. Though a solenoid is just a metal bar coiled around by wire that may or may not be electromagnet depending upon whether the current is flowing through it or not.
