Answer 1

Answer:

Activity 13.2 asks us to dust some iron filings near a bar magnet.

Activity 13.4 asks us to change the direction of current in a wire and see the deflection in the compass.

13.5 -The following activity is helpful in understanding the magnetic magnetic field pattern around a current carrying straight conductor.

13.7- The following activity shows that a current carrying conductor experiences a force when placed in a magnetic field

13.6-The following activity is useful in understanding the magnetic field pattern around a current carrying circular loop.

13.8 and 13.9- These activities are helpful in understanding the phenomenon of electomagnetic induction
