5differences between solenoid and bar magnet?? |
| Answer» \tThe bar magnet is a permanent magnet whereas a solenoid is an electromagnet ie, it acts as a magnet only when an electric current is passed through.\tWhen a bar magnet is cut into two halves, both the pieces act as a magnet with the same magnetic properties whereas when a solenoid is cut into two halves, they will have weaker fields.\tThe poles of the bar magnet are fixed whereas for a solenoid the poles can be altered.\tThe strength of the magnetic field of a bar magnet is fixed ie, unaltered whereas the strength of the magnetic field of a solenoid depends on the electric current that is passed through it. | |
