Magnetism and Matter: Class 12 Physics (UP Board) important questions and practice
Magnetism and Matter is chapter 5 of 14 in UP Board Class 12 Physics. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Bar magnet as an equivalent solenoid and its field lines
- Magnetic dipole moment and torque on a magnetic dipole in a uniform field
- Magnetic field of a bar magnet along the axis and equatorial line
- Gauss's law for magnetism
- Magnetisation, magnetic intensity, susceptibility and permeability
- Dia-, para- and ferromagnetic substances with examples (hysteresis removed in CBSE)
What examiners usually ask
- Show that a current-carrying solenoid behaves like a bar magnet and derive the field on its axis
- Distinguish between diamagnetic, paramagnetic and ferromagnetic substances on the basis of susceptibility and behaviour in a field
- A bar magnet of moment 1.5 J/T lies along a field of 0.22 T; find the work done to turn it through 90 degrees and the torque in that position
Exam tip
The three-way comparison table (susceptibility sign and magnitude, relative permeability, field-line behaviour, examples) is a certain question; also know that the Earth's magnetism elements were removed from the CBSE syllabus but remain in some state boards.
