Worksheet 1. Experiment.
To investigate the force on a current-carrying conductor in a magnetic field
stiff wire, strong permanent magnet, 9V dry cell, switch, insulated copper
a stiff wire in to a shape of a swing (Fig.1). Connect it to the copper wires,
dry cell and switch to form a circuit.
the S pole of the magnet over the part of wire BC.
on the current. Observe the direction in which the wire swings.
the direction of the current by switching the polarity of the dry cell. In
which direction does the wire swing now?
the magnet so that the pole above the wire is now N pole. Repeat
step 3. Note the direction in which the wire moves.
the blanks by using the words( opposite, outwards, inwards). You may use them
more than one time.
the current flowing in direction , the wire swings outwards
from the magnet.
If the current reversed, the wire swings
in the opposite direction, i.e. inwards.
If the magnetic field is reversed, the
wire swings outwards,
