Explain the magnetic field of a bar magnet and that of a solenoid, and compare them.
Magnetic Field of a Bar Magnet: A bar magnet is a permanent magnet that generates a magnetic field around it. The magnetic field of a bar magnet can be described as follows: Magnetic Poles: A bar magnet has two poles—north (N) and south (S). The magnetic field lines emerge from the north pole and enter … Read more
