Hi Shogun
can u help out in November 1995 PAPer1 q.32
nid404:
Ans for 32 is B.
cuz the magnetic field lines have to be cut for a p.d to be induced.

How have the magnetic field lines been cut since we are not moving the magnet?
nid404:
the bar is inside the solenoid..it was moved into the solenoid,causing the field line to be cut. the rest r not correct anyways. For A the magnet is a part of the whole connection(absolutely wrong) for C the magnet is outside the solenoid and being rotated(if it were inside then a pd would be induced as rotating outside does not cut the field line and for D the magnet is being taken away from the solenoid it needs to be taken into it so that field lines can be cut
annie_angel:
wats da usual grade threshold for A in physics paper 1??
