Magnetism And Matter Class 12 Notes

CBSE Class 12 Physics Notes Chapter 5 – Magnetism and Matter

What happens to the dipole moment of a magnet?
When a magnet is experiencing a dipole moment m, and it is placed in a uniform magnetic field B, then it experiences:

• The force on it as zero
• The torque on it as m*B
• The potential energy can be said to be as -m*B. Where the zero of energy is determined when m is perpendicular to B

Gauss’s law for Magnetism:
Gauss’s law of magnetism points out the fact that the net magnetic flux through any surface which is closed tends to be Zero. Please refer Magnetism And Matter Class 12 Notes for more revision notes.
