Q3: <em>How is an electromagnet useful when compared to a permanent magnet?</em>
A3: <em>According to Toppr, The main advantage of an electromagnet over a permanent magnet is that we can quickly change the magnetic field by controlling the amount of electric current in the winding. The magnetic field created by an electromagnet is proportional to both the number of turns in the winding and the current in the wire.</em>
