Questions from Subject Experts Solutions for Exercise 1: SELF-ASSESSMENT TEST with Hints & Solutions
A student fixes a sheet of white paper on a drawing board. He places a bar magnet in the centre of it. He sprinkles some iron filings uniformly around the bar magnet. Then he taps the board gently and observes that the iron filings arrange themselves in a particular pattern. What does the crowding of iron filings at the end of the magnet indicate?

On what factors do the direction of force experienced by a conductor when placed in a magnetic field depend?
Under what conditions is the force experienced by a current carrying conductor placed in a uniform magnetic field maximum?
Name and state the rule which gives the direction of force experienced by a current carrying conductor placed in a magnetic field.
Two coils C1 and C2 are wrapped around a non conducting cylinder. Coil C1 is connected to a battery and key and C2 with galvanometer G. On pressing the key (K), current starts flowing in the coil C1. State your observation in the galvanometer:
(i) When key K is pressed on.
(ii) When current in the coil C1 is switched off.
(iii) When the current is passed continuously through coil C1
(iv) Name and state the phenomenon responsible for the above observation. Write the name of the rule that is used to determine the direction of current produced in the phenomena.
