====== Chapter 14: Electromagnetism ======
This is a fourteenth chapter of the book Physics 12 published by Punjab Curriculum and Textbook Board, Lahore, Pakistan.

After studying this chapter, the students will be able to:

  * Appreciate that a force might act on a current carrying conductor placed in a magnetic field.
  * Define magnetic flux density and the tesla.
  * Derive and use the equation $F= BI L \sin \theta $ with directions.
  * Understand how the force on a current carrying conductor be used to measure the magnetic flux density of a magnetic field using a current balance.
  * Describe and sketch flux patterns due to a long straight wire.
  * Define magnetic flux and the weber
  * Derive and use the relation $\theta = B.A $.
  * Understand and describe Ampere's law.
  * Appreciate the use of Ampere's law to find magnetic flux density inside a solenoid.
  * Appreciate that there acts a force on a charged particle when it moves in a uniform magnetic field and in field.
  * Describe the deflection of beams of charged particles moving in a uniform magnetic field.
  * Understand and describe method to measure $e/m.$
  * Know the basic principle of cathode ray and appreciate its use.
  * Derive the expressi0n of torque due to couple acting on a coil.
  * Know the principle, construction and working of a galvanometer.
  * Know how a galvanometer is converted into a voltmeter and an ammeter.
  * Describe and appreciate the use of AVO meter/multimeter.
  * Read through analogue scale and digital display on electrical meters.
