Al-Huda Science Academy has designed Class 12 MCQs Physics Chapter 14 Electromagnetism for board, MdCat and ECAT preparation. These MCQs help students to prepare for their entry test papers.
Chapter 14 Electromagnetism includes topics:
- Electromagnetism
- Force on a current carrying coil in magnetic field
- Magnetic Flux and Magnetic Density
- Ampere’s law
- Determination of flux density
- Force on a moving charge in a magnetic field
- Lorentz Force
- Determination of e/m
- CRO – Cathode Ray Oscilloscope
- Torque on a current carrying coil
